Sentences

Mainly sentences are categorized into four moods as follows:

Declarative sentences give information about something. They have a subject and a predicate. A predicate is made of a verb and sometimes a subject complement or an object complement. Here are the examples.

Declarative sentences are also categorized into two groups:

Affirmative sentences have affirmative verbs. We use negation rules to make negative sentences. Check out the examples.

We use interrogative mood to ask questions about something or to ask for information about something. Usually, there is an inversion to make interrogative sentences. Here are the examples.

Interrogatory sentences are categorized into two groups.

Wh-questions start with an interrogative-word and yes/no questions start with an auxiliary verb. Check the examples.

Imperative sentences are used to give orders. They are usually made of only one word which is actually the imperative verb. Here are the examples.

There are also two types of imperative sentences in English.

The subject of an imperative sentence is the pronoun 'you' that is usually omitted because it can be implied from the meaning of the imperative verb.

Some English learners tend to consider the modal verbs should and must as imperative verbs, which is actually wrong. Imperative verbs are capable of being used without subjects, however, you can never use a modal verb alone as an imperative verb. So, If you can omit the subject without harming the formation of the sentence then the verb is an imperative verb. Here are the examples.

Since imperative verbs are all main verbs, to make negative imperatives all you have to do is to add don't to the beginning of an imperative sentence. For example:

Exclamatory sentences are used to show surprises. Commonly, exclamations are formed by the words 'what' and 'how.' Here are the examples.

Every sentence is followed by a particular punctuation mark. You can see every punctuation for each sentence on teh following list:

Based on their structure, sentences are categorized into four groups:

Simple sentences are formed by a subject as the doer of activity and a predicate as the action. The important point about simple sentences is that they are not followed by dependent or subordinate clauses. For example:

Compound sentences are two independent sentences that are linked with linking words or conjunctions, and semicolon. Here are the examples.

Complex sentences are formed with an independent clause and at least one dependent clause linked to the independent clause. Here are the examples.

Compound-complex sentences merge compound sentences with complex sentences. A compound-complex sentence has at least two independent clauses and one dependent clause. Here are the examples.
