Word class, also known as parts of speech, just means the type of word (noun, verb, adjective, etc.). Some words represent things, others represent actions, and some are just for description. It’s important to know parts of speech in grammar because different word classes have different rules.
- Noun—represents people, places, things, and concepts
- Verb—represents actions
- Adjective—describes nouns
- Adverb—describes verbs, adjectives, and other adverbs
- Pronoun—represents other nouns to save time
- Auxiliary verb (helper verb)—a special type of verb used in supportive roles like conjugation
- Preposition—shows relationships of direction, time, location, and space
- Determiner—identifies characteristics of a noun and is necessary in certain grammar situations
- Conjunction—joins together other words, phrases, or clauses
- Interjection—expresses sudden feelings to mimic speech in writing (used informally)
Example: Wow, he has quickly grown into a beautiful and healthy cat!
