• Pronouns: Words that replace nouns (e.g., he, she, they).

• Verbs: Action or state of being words (e.g., run, is, have).

• Adjectives: Words that describe nouns (e.g., beautiful, large, intelligent).

• Adverbs: Words that modify verbs, adjectives, or other adverbs (e.g., quickly, very, well).

• Prepositions: Words that show relationships between nouns/pronouns and other words (e.g., in, on, under).

• Conjunctions: Words that connect clauses or sentences (e.g., and, but, because).

• Interjections: Words used to express strong emotions (e.g., Wow!, Ouch!).
