The sentence

In the process of communication words combine to form utterances. Most utterances fall into two groups: sentences and non-sentence utterances.

Non-sentence utterances are:

1. Vocatives: Charles! Mr.West!

2. Yes-no answers.

3. Interjections: Hi! Dear me!

4. Conversational formulas: Thank you. Bye-bye.

The sentence is a minimal text unit which may be used in communication to express a complete message.

From the point of view of their structure sentences fall into the following types:
