English word classes encompass nouns, verbs, pronouns, adjectives, adverbs, cardinal numbers, articles, prepositions, conjunctions, and interjections. Nouns can function as subjects, objects, and sometimes as attributive adjectives. Verbs serve as predicates.

Here are the abbreviations and uses for English word classes:

- Prep = Preposition; used to connect words with other words or to show relationships.

- Pron = Pronoun; used to replace a noun.

- N = Noun; a person, place, thing, or idea.

- U = Uncountable Noun; cannot be counted.

- C = Countable Noun; can be counted.

- V = Verb; action words that show state of being or doing.

- Vi = Intransitive Verb; does not need a direct object.

- Vt = Transitive Verb; requires a direct object.

- Conj = Conjunction; connects words, phrases, or clauses.

- Adj = Adjective; describes or modifies a noun or pronoun.

- Adv = Adverb; describes or modifies a verb, adjective, or another adverb.

- Art = Article; specifies if the noun is specific or non-specific.

- Num = Number; used with nouns to indicate quantity.

- Int = Interjection; a word or phrase used to express a feeling.

The uses of English word classes are as follows:

1. Nouns serve as subjects, objects, and can act as attributive adjectives.

2. Verbs act as predicates and can also be found in infinitive forms (e.g., "to do").

3. Adjectives modify nouns and can also be used as predicates.

4. Adverbs can stand alone and modify verbs, adjectives, or other adverbs.

5. Pronouns replace nouns as subjects, objects, or predicates.

6. Prepositions combine with verbs to form prepositional phrases and can also modify nouns.

7. Cardinal numbers accompany nouns to indicate quantity.

8. Conjunctions join sentences or elements within a sentence and express relationships.

9. Articles specify if a noun is specific ("the") or non-specific ("a/an").

10. Interjections express emotions such as surprise, anger, or joy.
