This document introduces the eight traditional parts of speech in English grammar: nouns, verbs, adjectives, adverbs, pronouns, prepositions, conjunctions, and interjections. It provides examples for each part of speech and describes their basic functions. While these are the traditional eight parts, modern linguists classify words into more specific categories. The four main parts - nouns, verbs, adjectives, and adverbs - are considered form classes as they can change form through inflectional or derivational morphemes.
