Understanding Parts of Speech

Every word in the English language belongs to one of eight categories called "parts of speech." Understanding these categories is fundamental to mastering grammar and improving your vocabulary.

The Eight Parts of Speech

Collective nouns: groups (team, flock, committee)

Examples:

Courage is more important than strength.

2. Pronouns

Definition: Words that replace nouns to avoid repetition.

Types:
