These notes cover the essential components of English grammar necessary for understanding sentence structure and usage.

Nouns signify individuals, locations, objects, or concepts, providing clarity (e.g., cat, city, happiness).
Pronouns serve as substitutes for nouns, reducing repetition (e.g., he, she, it).
Verbs express actions or states of being, forming the core of sentences (e.g., run, is).
Adjectives enhance sentences by adding descriptive qualities to nouns (e.g., blue, tall).
Adverbs modify verbs, adjectives, or other adverbs, often explaining how actions are performed (e.g., quickly, very).
Prepositions indicate relationships between nouns (or pronouns) and other sentence elements (e.g., in, on, at).
Conjunctions connect words, phrases, or clauses, improving sentence flow (e.g., and, but, or).
Interjections convey emotions or reactions spontaneously (e.g., oh, wow).

Simple sentences consist of a subject and a predicate, delivering a complete thought (e.g., The dog barks).
Compound sentences join two independent clauses with a conjunction, allowing thoughts to be connected (e.g., The dog barks, and the cat sleeps).
Complex sentences feature an independent clause and at least one dependent clause, adding depth (e.g., The dog barks when the mailman arrives).
Compound-complex sentences combine multiple independent clauses with at least one dependent clause, showcasing intricate relationships (e.g., The dog barks, and the cat sleeps when it rains).

Present tense conveys ongoing actions or states occurring presently (e.g., I eat).
Past tense describes completed actions that took place earlier (e.g., I ate).
Future tense articulates actions anticipated to take place (e.g., I will eat).
Perfect tenses signify completed actions in relation to other times (e.g., I have eaten, I had eaten, I will have eaten).

Run-on sentences incorrectly merge two independent clauses without proper punctuation, creating confusion.
Fragments are incomplete sentences lacking a main clause, failing to express a complete thought.
Misplaced modifiers disrupt sentence clarity by being inaccurately positioned relative to the words they modify.

Active voice emphasizes the subject performing the action, enhancing clarity (e.g., The chef cooked the meal).
Passive voice focuses on the subject receiving the action, which can obscure who performs it (e.g., The meal was cooked by the chef).

Independent clauses can function as standalone sentences, presenting complete ideas (e.g., She enjoys reading).
Dependent clauses cannot stand alone and rely on independent clauses for context (e.g., Because she enjoys reading...).
