Assertive/Declarative

An assertive sentence is a statement that makes a declaration, states a fact, or expresses an opinion. Also known as a declarative sentence, it conveys information in a straightforward way and typically ends with a period.

Examples include "The sky is blue" or "I like to read books". 

Key characteristics of an assertive sentence

Makes a statement: Its main purpose is to declare or state something, rather than ask a question or give a command.

States facts or opinions: It can be based on a fact or a personal belief.

Ends with a period: The punctuation at the end of the sentence is a full stop.
