Most Important vs. Most Importantly – Easy Usage Guide (+14 Examples)

When we use “important” as a noun or an adverb, it slightly changes the phrase’s meaning. It’s good to know what this differentiation becomes when we use it so we can tell when to use one over the other.

Is It “Most Important” Or “Most Importantly”?

The correct spelling is “most important,” and we use “important” in the noun form in this case. It means that the object in the sentence is the most important thing of all. “Most importantly” does still get used, but “important” is an adverb here.

Is “But Most Importantly” Grammatically Correct?

Some people believe that starting a sentence with “but” is incorrect; however, it actually works really well in this situation.

“But most importantly” is grammatically correct, and you’re able to start the sentence with “but” when you use it.

Typically, “but most importantly” is the most common way to use “most importantly” as a phrase. That’s because in the adverb form, “importantly” shows when a particular thing is the most important thing in that sentence to mention.

For example, if you made a list, you could introduce the sentence after as “but most importantly,” to show the most important thing of that list.

Does The Same Rule Apply To “More Important” And “More Importantly”?

The same rules are extended when we replace the word “most” with “more.”

“More important” is the comparative adjective, while “most important” is the superlative adjective. However, both of these words follow the same rules when we use them in a sentence in this manner.

“More importantly” is also correct, but we usually have to start by writing “but,” just like we mentioned above.

Should You Place A Comma After “Most Important” And “Most Importantly”?

Usually, we don’t need to place a comma after “most important” if we’re using it in a sentence as an adjective. For example,

  • The most important thing.

This shows that we’re modifying “thing” in the sentence, and a comma is not needed.

However, “most importantly” is a construct designed to introduce an idea. That means we need to include a comma after it.

  • Most importantly, you’re all safe.
