It Is Necessary (Formal)

“It is necessary” is great as a formal way to say “it is a must.” It’s much more apparent, as it shows someone they must complete something because it’s vital to a specific operation.

Why not try it when emailing employees and telling them to complete certain tasks? If those tasks are vital to your company’s profits, you must let them know they are necessary.

The phrase adds urgency to your emails, showing that they have to treat it with the utmost importance. It helps that it’s very professional, too, without sounding too demanding.

Of course, “it is necessary” and “it is a must” are both effective formally. We recommend using either one in formal writing to show that an employee must complete a task as soon as possible.

Here are some examples showing you how to use the formal variation:

Dear Roger,

It is necessary that you complete this work before the next task. I cannot wait any longer.


I’m sorry, but it is necessary. We have a strict deadline that we must abide by.

There’s No Maybe About It (Informal)

“There’s no maybe about it” is a great informal synonym for “it is a must.” Be careful with it, though. It’s not friendly and can be quite demanding if you’re trying to get someone to do something for you.

You should use this phrase to get a friend to complete a task. It suggests that they can’t say no, meaning it’s a very important task requiring their attention. You should only do this when you’re certain your friend can help you, even if they’re a bit reserved at first.

We don’t recommend using “there’s no maybe about it” in formal writing. There’s nothing professional about it. You should stick with “it is a must” to show that someone must complete a task for you.

Check out how to use it with the following examples:

Oh, there’s no maybe about it, Scotty! You’ve got to complete it as written, I’m afraid.

There’s no maybe about it, so I would try and do it! I don’t think Sam is going to be happy if you ignore him.

Is It Correct to Say “It Is a Must”?

“It is a must” is correct. You might not know this, but “must” is a noun in this instance. Therefore, it makes sense for “a” to come before it to describe it as a singular entity.

The sentence no longer makes sense if you remove “a.” For instance:

  • Correct: It is a must that you do this for me, though.
  • Incorrect: It is must that you complete this task.

“It is must” makes no grammatical sense, so it’s best to avoid using it to show that “must” is a noun.

When used as a noun, “must” means a necessity. It shows the relevance of a specific task and that you must complete it.
