It’s impossible to give an exact number for all the things in English grammar. There are many aspects, such as parts of speech, sentence structure, punctuation, and word usage.
Parts of Speech:
- Nouns: People, places, things, and ideas (e.g., dog, school, book, love).
- Pronouns: Replace nouns (e.g., he, she, it, they).
- Verbs: Actions or states of being (e.g., run, sleep, be, have).
- Adjectives: Describe nouns (e.g., big, red, happy).
- Adverbs: Describe verbs, adjectives, or other adverbs (e.g., quickly, very, really).
- Prepositions: Show relationships between words (e.g., on, in, under, to).
- Conjunctions: Connect words, phrases, or clauses (e.g., and, but, or, because).
- Determiners: Specify nouns (e.g., a, the, this, that).
Sentence Structure:
- Subjects: The person or thing doing the action (e.g., The cat).
- Predicates: The part of the sentence that tells what the subject does or is (e.g., sat on the mat).
- Objects: Receive the action of the verb (e.g., the ball in "The boy kicked the ball").
Punctuation:
- Periods (.)
- Commas (,)
- Question marks (?)
- Exclamation marks (!)
- Semicolons (;)
- Colons (:)
- Apostrophes (')
Word Usage:
- Tense: Past, present, future (e.g., walked, walks, will walk).
- Voice: Active (subject performs the action) or passive (subject receives the action).
- Mood: Indicative (statements of fact), imperative (commands), subjunctive (hypothetical situations).
While it's hard to count everything in English grammar, these are some of the core components.
