What is an Affirmative Sentence? Formation and Examples

English sentences are grouped into two main types: affirmative and negative. While negative sentences deny something, affirmative sentences do the opposite — they state or confirm a fact, action, or idea.

Affirmative sentences are the most common type in both speech and writing. They help us express what is true, what happens, or what someone believes.

What Is an Affirmative Sentence?

An affirmative sentence is a sentence that states something is true or correct. It affirms or confirms an action, event, or condition — without using negative words like not, never, no, nothing, nobody, etc.

Examples:

• She enjoys reading.
• We are going to the market.
• I passed the exam.
• He will arrive soon.
• The sun rises in the east.

These sentences clearly state facts, actions, or situations without denying or contradicting them.
