If you’ve ever paused before writing most important or most importantly, you’re not alone.
These two expressions look similar, but they don’t always work the same way.
The confusion usually comes from the words important and importantly.
Since one is an adjective and the other is an adverb, many English learners assume that only one of the two expressions can be correct.
In reality, both are grammatically acceptable, but they serve different purposes and fit different sentence structures.
Understanding the distinction matters because it can make your writing sound more natural, polished, and precise.
Whether you’re writing an academic essay, a business email, a report, or simply speaking in everyday English, choosing the right expression helps your message come across clearly.
In this guide, you’ll learn:
- Whether most important or most importantly is correct
- The grammatical difference between them
- When each expression sounds most natural
- Most Important vs Most Importantly
- Common mistakes to avoid
- Plenty of real-world examples
By the end, you’ll know exactly which expression to choose in any situation.
Quick Answer
Both most important and most importantly are correct, but they are used differently.
- Most important is an adjective phrase that describes a noun or functions as a subject complement.
- Most importantly is an adverbial phrase that introduces or emphasizes the most significant point in a sentence.
Examples
✅ Most important, remember to save your work before closing the program.
✅ Most importantly, remember to save your work before closing the program.
Although both are accepted in modern English, most importantly is often preferred when introducing the final or most significant point, while most important is common when describing something or acting as a sentence modifier in more formal or concise writing.

Understanding Most Important
Most important is the superlative form of the adjective important. It describes the person, thing, idea, or action that has the highest level of importance.
Simply put, it answers the question:
Which one matters the most?
Examples
- Health is the most important thing in life.
- Most Important vs Most Importantly
- She made the most important decision of her career.
- Customer satisfaction remains our most important priority.
In these examples, most important directly describes a noun.
Grammar
The word important is an adjective.
Adding most creates the superlative adjective.
Pattern
the + most + adjective
Examples:
- Most Important vs Most Importantly
- the most important factor
- the most important question
- Most Important vs Most Importantly
Because adjectives describe nouns, most important naturally appears alongside nouns.
Why It Sometimes Appears Alone
You may also see sentences like:
Most important, always tell the truth.
At first glance, this looks unusual because there isn’t a noun immediately after most important.
In fact, this is a long-established construction in English where an adjective phrase acts as a sentence modifier. Here, most important means something like:
- Above all
- The most important thing is this
- Most Important vs Most Importantly
The implied wording is understood by the reader, making the sentence concise without changing its meaning.
Origin
The adjective important entered English in the late 16th century through French, ultimately deriving from the Latin importare, meaning “to bring in” or “to signify.”
Over time, important came to describe anything carrying great significance or value. The superlative form, most important, naturally developed to express the highest degree of importance among several things.
Because English often allows adjective phrases to function independently in certain contexts, expressions such as Most important, … have appeared in literature, journalism, and formal writing for generations.
Pronunciation
Most important
IPA (UK): /məʊst ɪmˈpɔːtənt/
IPA (US): /moʊst ɪmˈpɔːrtənt/
Stress falls on the second syllable of important:
im-POR-tant
When to Use Most Important
1. To Describe Something
This is the most common use.
Examples:
- Family is the most important part of my life.
- Most Important vs Most Importantly
- Trust is the most important quality in a friendship.
2. In Academic Writing
Researchers often compare variables or findings.
Examples:
- The most important variable was temperature.
- Cost remains the most important consideration.
- Education is one of the most important predictors of success.
3. In Business Writing
Professionals frequently describe priorities.
Examples:
- Most Important vs Most Importantly
- Customer feedback is the most important source of improvement.
- Quality remains the company’s most important value.
4. As an Introductory Emphasis
Less common than the descriptive use but still correct.
Examples:
- Most Important vs Most Importantly
- Most important, listen carefully.
- Most important, never stop learning.
In this use, the phrase emphasizes what follows rather than describing a specific noun.
Everyday Usage
Native speakers often use most important naturally in conversation.
Examples:
- What’s the most important thing to remember?
- That’s the most important part.
- Most Important vs Most Importantly
- Money isn’t the most important thing.
Because it directly identifies what matters most, this expression feels straightforward and natural.
Professional Usage
You’ll often find most important in:
- business reports
- presentations
- executive summaries
- proposals
- Most Important vs Most Importantly
- research papers
Examples:
- Employee safety is our most important responsibility.
- Data accuracy is the most important requirement.
- The most important objective is long-term growth.
Its descriptive role makes it especially useful when identifying priorities or ranking factors.
Common Mistakes
Mistake 1
❌ Most importantly factor
✅ Most important factor
Why?
An adjective—not an adverb—is needed to describe the noun factor.
Mistake 2
❌ The most importantly reason
✅ The most important reason
Again, reason is a noun, so it requires an adjective.
Mistake 3
❌ She made the most importantly decision.
✅ She made the most important decision.
The adjective important correctly modifies decision.
Quick Tip
Ask yourself:
Am I describing a person, place, thing, or idea?
If the answer is yes, you almost certainly need most important.
Understanding Most Importantly
Most importantly is an adverbial expression used to introduce or emphasize the point that the speaker or writer considers the most significant.
It often means:
- Above all
- Most Important vs Most Importantly
- Most of all
- More importantly (in a final or strongest sense)
Rather than describing a noun, it comments on the importance of the statement that follows.
Grammar
The word importantly is an adverb, formed by adding -ly to the adjective important.
Adverbs typically modify:
- verbs
- adjectives
- Most Important vs Most Importantly
- or entire clauses
In most importantly, the phrase usually modifies the entire sentence rather than a single word.
For example:
Most importantly, everyone remained safe.
Here, the phrase tells the reader that the upcoming statement is the key takeaway.
Origin
Adverbs ending in -ly have long been used as sentence adverbs in English to express the speaker’s attitude or organize information.
Expressions such as:
- Fortunately,
- Interestingly,
- Surprisingly,
- Importantly,
all function in a similar way.
Most importantly emerged as a natural extension of this pattern, allowing writers to introduce the point they consider most significant.
Today, it is widely accepted in both formal and informal English.
Pronunciation
Most importantly
IPA (UK): /məʊst ɪmˈpɔːtəntli/
IPA (US): /moʊst ɪmˈpɔːrtəntli/
The added -ly creates one extra syllable while keeping the primary stress on POR.
When to Use Most Importantly
1. To Introduce the Key Point
This is the most common use.
Examples:
- Most importantly, everyone arrived safely.
- Most importantly, we learned from the experience.
- Most Important vs Most Importantly
The phrase signals that what follows deserves the reader’s greatest attention.
2. In Academic Writing
Writers often use it to emphasize conclusions or findings.
Examples:
- Most importantly, the results support the original hypothesis.
- Most importantly, the study highlights the need for further research.
- Most importantly, the evidence remained consistent across all groups.
3. In Business Communication
It helps prioritize key messages.
Examples:
- Most Important vs Most Importantly
- Most importantly, we met every safety requirement.
- Most importantly, the project stayed within budget.
4. In Everyday Conversation
Although slightly more formal than most important, it is common in speech.
Examples:
- Most importantly, did everyone have fun?
- Most Important vs Most Importantly
- Most importantly, don’t forget to call me.
Common Mistakes
Mistake 1
❌ The most importantly meeting
✅ The most important meeting
An adverb cannot modify a noun.
Mistake 2
❌ Our most importantly goal
✅ Our most important goal
Again, goal needs an adjective.
Mistake 3
❌ Most importantly lesson
✅ Most important lesson
When the phrase directly describes a noun, use the adjective important, not the adverb importantly.
Quick Tip
If you’re introducing the main point of an entire sentence, most importantly is often the better choice.
If you’re describing a noun, choose most important.
Key Differences Between Most Important and Most Importantly
Although most important and most importantly are closely related, they are not always interchangeable. The biggest difference lies in grammar and sentence function.
Here’s a simple comparison:
- Most important is an adjective phrase. It usually describes a noun or acts as a complement after a linking verb.
- Most importantly is an adverbial phrase. It modifies an entire clause or sentence by highlighting the most significant point.
Think of it this way:
- Most important answers “Which thing matters most?”
- Most importantly answers “What is the most important point I’m about to make?”
Side-by-Side Comparison
| Most Important | Most Importantly |
|---|---|
| Describes nouns | Modifies a sentence or clause |
| Adjective phrase | Adverbial phrase |
| Identifies the highest degree of importance | Introduces the key point |
| Common in descriptions | Common in transitions and emphasis |
| Example: The most important lesson… | Example: Most importantly, we learned… |
Grammar Explanation
To use these expressions confidently, it helps to understand the grammar behind them.
Most Important Is an Adjective Phrase
The word important is an adjective.
Adjectives describe or identify nouns.
Examples:
- the most important question
- Most Important vs Most Importantly
- the most important chapter
In each sentence, important tells us more about the noun.
Sentence Pattern
the + most + adjective + noun
Examples:
- the most important rule
- the most important decision
- the most important factor
It Can Also Be a Subject Complement
After linking verbs such as be, seem, become, remain, and appear, adjectives describe the subject.
Examples:
- Most Important vs Most Importantly
- Safety remains the most important priority.
- Most Important vs Most Importantly
Notice that important still functions as an adjective.
Most Importantly Is an Adverbial Expression
The adverb importantly usually comments on an entire statement rather than modifying a single word.
Examples:
- Most importantly, everyone stayed safe.
- Most Important vs Most Importantly
- Most importantly, she enjoyed the experience.
Here, the phrase signals:
“Pay special attention to what comes next.”
Why Both Can Introduce a Sentence
Many learners wonder why these are both acceptable:
Most important, remember your passport.
and
Most importantly, remember your passport.
The answer lies in sentence modifiers.
Using Most Important
This construction is actually a shortened form of:
The most important thing is this: remember your passport.
Over time, English speakers omitted the repeated words because the meaning remained clear.
Using Most Importantly
This version works because English frequently uses sentence adverbs.
Compare:
- Most Important vs Most Importantly
- Surprisingly, she agreed.
- Frankly, I disagree.
- Most Important vs Most Importantly
The adverb comments on the whole sentence.
Sentence Position
Both expressions most often appear at the beginning of a sentence, but their placement differs slightly.
Beginning of a Sentence
Most Important
✔ Most important, check the instructions carefully.
Most Importantly
✔ Most importantly, check the instructions carefully.
Middle of a Sentence
Most Important
✔ The most important lesson was patience.
Most Importantly
✔ The project succeeded and, most importantly, stayed within budget.
End of a Sentence
Ending a sentence with either expression is uncommon unless the sentence is restructured.
Example:
✔ This is the most important.
✔ Everyone stayed safe, most importantly.
However, native speakers usually rewrite the second sentence for smoother flow:
✔ Most importantly, everyone stayed safe.
Parts of Speech Explained
| Word | Part of Speech | Example |
|---|---|---|
| important | Adjective | an important meeting |
| importantly | Adverb | Importantly, the results improved. |
| most important | Superlative adjective phrase | the most important reason |
| most importantly | Adverbial phrase | Most importantly, everyone agreed. |
Understanding this distinction eliminates most confusion.
Why People Get Confused
There are several reasons these expressions are commonly mixed up.
1. They Share the Same Root Word
Both come from important, so many learners assume they perform the same grammatical function.
They don’t.
2. Both Can Begin a Sentence
Seeing both of these can be confusing:
- Most Important vs Most Importantly
- Most importantly, be honest.
Because both are accepted, learners often wonder if one must be wrong.
The answer is no—they simply emphasize the sentence in different grammatical ways.
3. School Grammar Rules
Many people learned that:
adjectives describe nouns
and
adverbs describe verbs.
While generally true, English also has sentence adverbs and sentence-modifying adjective phrases, which makes the language more flexible than those basic rules suggest.
Which One Is More Common?
In modern English, most importantly is slightly more common when introducing the final or strongest point in a list or argument.
For example:
- Most Important vs Most Importantly
- We reduced costs.
- Most importantly, customers were happier.
Meanwhile, most important overwhelmingly dominates when modifying nouns.
Examples:
- the most important question
- Most Important vs Most Importantly
- the most important lesson
These are fixed, natural patterns used every day.
Which One Sounds More Natural?
The answer depends on the sentence.
When Describing a Noun
Natural:
✔ the most important decision
Unnatural:
✘ the most importantly decision
When Introducing Your Main Point
Natural:
✔ Most importantly, trust yourself.
Also acceptable:
✔ Most important, trust yourself.
Many speakers prefer most importantly because it clearly signals an introductory remark.
Formal vs. Informal Usage
| Situation | Most Important | Most Importantly |
|---|---|---|
| Everyday conversation | ✔ Very common | ✔ Common |
| Business writing | ✔ Excellent | ✔ Excellent |
| Academic writing | ✔ Excellent | ✔ Excellent |
| Journalism | ✔ Common | ✔ Common |
| Presentations | ✔ Common | ✔ Very common |
| Emails | ✔ Common | ✔ Common |
| Speeches | ✔ Common | ✔ Very common |
Neither expression is considered informal.
Both are fully acceptable in professional writing.
Style Guide Recommendations
Major English style guides and dictionaries generally accept both forms, though they recognize that they serve different grammatical functions.
AP Style
The Associated Press Stylebook focuses on clarity and concise writing rather than banning either expression.
In news writing:
- Most important is preferred when describing a noun.
- Most importantly is appropriate when introducing the key point of a sentence.
The recommendation is to choose the form that fits the grammar—not to replace one with the other automatically.
The Chicago Manual of Style
The Chicago Manual of Style likewise accepts both expressions.
Chicago emphasizes grammatical accuracy and natural sentence structure.
Editors following Chicago typically write:
- the most important issue
- Most importantly, readers should understand…
Both are considered standard written English.
Oxford English Usage
Oxford recognizes importantly as a legitimate sentence adverb.
Older usage guides sometimes criticized introductory adverbs like importantly, but that objection has largely disappeared from modern editing practice.
Today, Most importantly, is widely accepted in books, journalism, and academic writing.
Cambridge English
Cambridge English treats important and importantly according to their grammatical roles:
- adjective → describes nouns
- adverb → comments on actions or entire clauses
This reflects current standard English usage.
Merriam-Webster
Merriam-Webster notes that importantly has long been used as a sentence adverb and is well established in educated English.
In other words:
✔ Most importantly is not a modern mistake.
It has a long history of accepted use.
Historical Perspective
Interestingly, debates about importantly date back more than a century.
Some traditional grammarians argued that only adjectives should introduce statements.
For example, they preferred:
More important, …
instead of
More importantly, …
Modern linguists largely reject this restriction because English naturally allows many sentence adverbs:
- Most Important vs Most Importantly
- Fortunately,
- Interestingly,
- Sadly,
- Surprisingly,
- Most Important vs Most Importantly
As a result, both more importantly and most importantly have become firmly established in standard English.
American English vs. British English
There is no major difference between American and British English in the use of these expressions.
| American English | British English |
|---|---|
| most important ✔ | most important ✔ |
| most importantly ✔ | most importantly ✔ |
Writers in both varieties use:
- the most important issue
- Most importantly, we succeeded.
Regional preference is minimal.
Professional Writing
In business documents, clarity is more important than following outdated rules.
Consider this example:
We improved customer support, reduced costs, and, most importantly, increased customer satisfaction.
The adverb clearly signals the main takeaway.
Now compare:
Customer satisfaction remains our most important goal.
Here, the adjective correctly describes goal.
Both sentences are excellent because each expression fits its grammatical role.
Academic Writing
Academic writing values precision.
Researchers often write:
- Most Important vs Most Importantly
- The most important limitation involved sample size.
When highlighting conclusions, they frequently write:
Most importantly, the findings support previous research.
This structure guides readers toward the author’s key conclusion without sounding overly dramatic.
Editorial Recommendation
From an editor’s perspective, the best choice is usually simple:
- Use most important when you’re describing something.
- Use most importantly when you’re introducing the point you want readers to remember most.
Avoid choosing one expression simply because you’ve heard it’s “more correct.” In contemporary English, both are standard when used in the appropriate grammatical context.
Real-Life Examples of Most Important vs. Most Importantly
The best way to master these expressions is to see them in context. Below are original examples from everyday conversations, business communication, academic writing, emails, social media, and more.
Everyday Conversation

Key Pattern to Remember
Notice the difference:
Describing Something
✔ the most important rule
✔ the most important lesson
✔ the most important question
Highlighting the Main Point
✔ Most importantly, everyone stayed safe.
✔ Most importantly, we met our goals.
✔ Most importantly, customers were satisfied.
Common Mistakes
Even advanced English speakers sometimes confuse these expressions. Here are the mistakes you should avoid.
Mistake 1: Using an Adverb Before a Noun
❌ The most importantly reason is cost.
Why It’s Wrong
The noun reason needs an adjective.
Correct
✔ The most important reason is cost.
Mistake 2: Using Importantly as a Noun Modifier
❌ Our most importantly objective is quality.
Correct
✔ Our most important objective is quality.
Mistake 3: Assuming Most Importantly Is Always Better
Some writers believe that every introductory sentence must begin with most importantly.
Not true.
Both are correct:
✔ Most important, stay calm.
✔ Most importantly, stay calm.
The second is slightly more common in modern writing, but the first is also standard English.
Mistake 4: Thinking One Is Incorrect
Many learners ask:
Is most important wrong?
No.
Others ask:
Is most importantly wrong?
Also no.
The real question is whether the phrase fits the sentence grammatically.
Mistake 5: Forgetting the Comma
When most importantly introduces a sentence, it is normally followed by a comma.
✔ Most importantly, everyone agreed.
Not:
✘ Most importantly everyone agreed.
Likewise:
✔ Most important, everyone agreed.
Which One Should You Choose?
Ask yourself one simple question:
Am I Describing a Noun?
If yes:
Use most important.
Examples:
- the most important lesson
- Most Important vs Most Importantly
- the most important person
Am I Introducing My Main Point?
If yes:
Use most importantly.
Examples:
- Most importantly, be honest.
- Most importantly, everyone remained safe.
- Most Important vs Most Importantly
Memory Tricks
A good memory trick can save you from second-guessing yourself.
Trick #1: The “Noun Test”
If a noun comes right after the expression, choose most important.
Examples:
- most important rule
- Most Important vs Most Importantly
- most important question
Think:
Important describes things.
Trick #2: The “Announcement Test”
If you’re about to announce your biggest point, choose most importantly.
Think of it as saying:
“Here’s what matters most.”
Example:
Most importantly, everyone was safe.
Trick #3: Remove the Phrase
Take the introductory phrase away.
Example:
Most importantly, we finished on time.
Without it:
We finished on time.
The sentence still works.
That means most importantly is simply emphasizing the statement.
Trick #4: Look for -ly
Words ending in -ly are often adverbs.
Adverbs frequently comment on an entire sentence.
Examples:
- Fortunately,
- Clearly,
- Most Important vs Most Importantly
- Importantly,
- Most importantly
This pattern makes it easier to recognize when an adverbial expression is appropriate.
Trick #5: Remember This Formula
Describing = Most Important
Emphasizing = Most Importantly
If you remember only one rule, make it this one.

Frequently
1. Is it most important or most importantly?
Both are correct, but they serve different grammatical purposes.
- Most Important vs Most Importantly
- Use most importantly when introducing or emphasizing the main point of a sentence.
Examples:
- Most Important vs Most Importantly
- Most importantly, everyone stayed safe.
2. Which is more grammatically correct: most important or most importantly?
Neither is inherently more correct. The right choice depends on the sentence.
Choose most important if you need an adjective.
Choose most importantly if you need a sentence adverb.
For example:
✔ The most important reason is cost.
✔ Most importantly, we solved the problem.
3. Can I start a sentence with most importantly?
Yes.
Starting a sentence with most importantly is standard English and is widely accepted in academic, professional, and everyday writing.
Examples:
- Most Important vs Most Importantly
- Most importantly, read the instructions carefully.
- Most importantly, enjoy the experience.
Remember to place a comma after the introductory phrase.
4. Can I start a sentence with most important?
Yes.
Although slightly less common than most importantly, most important can also introduce a sentence.
Example:
- Most important, never stop asking questions.
This construction is understood as a shortened form of “The most important thing is this…” and has long been accepted in English.
5. Do most important and most importantly mean the same thing?
They express a similar idea—highlighting the greatest importance—but they are not used in exactly the same way.
- Most important identifies the thing with the highest importance.
- Most importantly emphasizes the significance of an entire statement.
Because their grammatical roles differ, they are not always interchangeable.
6. Which expression is more common?
It depends on the context.
When describing nouns, most important is far more common.
Examples:
- the most important issue
- Most Important vs Most Importantly
- the most important question
When introducing a key point, most importantly is often the preferred choice.
Example:
- Most importantly, everyone remained safe.
7. Is most importantly too informal for academic writing?
No.
Most importantly is widely used in academic articles, research papers, reports, and professional publications.
Examples:
- Most importantly, the findings support previous research.
- Most importantly, the evidence remained consistent throughout the study.
Many scholars use it to draw attention to their main conclusion.
8. What is the easiest way to remember the difference?
Use this simple rule:
- Most important = describing
- Most importantly = emphasizing
If a noun follows, use most important.
If you’re highlighting your biggest point, use most importantly.
This one rule will help you choose correctly in most situations.
Final Verdict
Both most important and most importantly are correct, but they are not interchangeable in every sentence.
Here’s the simplest way to decide:
Use most important when:
- Most Important vs Most Importantly
- You are identifying the thing with the highest importance.
- You are comparing priorities.
Examples:
- The most important lesson.
- Most Important vs Most Importantly
- The most important factor.
Use most importantly when:
- You are introducing your key message.
- You are emphasizing the main takeaway.
- You are guiding the reader toward the most significant point.
Examples:
- Most Important vs Most Importantly
- Most importantly, remember to ask questions.
- Most importantly, enjoy the journey.
Neither expression is “better” than the other. The best choice depends on what your sentence needs.
