I'm confused with imperative sentence.

Is " You must go to school right now." a imperative sentence? Thanks.

So is "Please leave the room soon." an imperative sentence?

Thank you.

No, that is a request. Leave the room now. That would be the imperative for. Imperative means an order not a request.

But in the website that Ms. Sue gives me. It says "Imperative sentences in the English language are the sentences that make a command or request"...

We do seem to have a difference of opinion here. However, here are two more sites that include requests using "please" as imperative sentences.

Yes, "You must go to school right now." is an example of an imperative sentence.

To determine if a sentence is imperative, you need to consider a few things:

1. Structure: Imperative sentences typically begin with the base form of a verb (also known as the verb's infinitive form) and do not have a subject explicitly stated. In this case, the base form of the verb "go" is used.

2. Command or request: Imperative sentences are usually used to give commands, make requests, or express instructions or demands. In this sentence, the speaker is giving the listener a command to go to school immediately.

3. Tone: Imperative sentences often have an implied or direct tone of urgency or importance. In this case, the use of the word "must" emphasizes the necessity and immediacy of the action.

By considering these factors, you can identify that "You must go to school right now." is indeed an imperative sentence.

No, that's a statement -- a declarative sentence. An imperative sentence with the same ideas would be this:

Go to school right now.

No, that is not an imperative sentence. Imperative sentences have an understood subject (you) that is not voiced or written in the sentence. To make it imperative, you'd say:

Go to school right now.
