Sentences
On this page
A sentence is a group of words that expresses a complete thought. It typically contains a subject (the person, place, thing, or idea that the sentence is about) and a predicate (which tells something about the subject). Here are key aspects of sentences in English:
Components of a Sentence#
Subject : The noun or pronoun that performs the action or is described in the sentence.
Predicate : The part of the sentence that tells what the subject does or is. It includes the verb and any objects or modifiers.
Example:
She (subject) runs quickly (predicate).

Sentence Structure#
Simple Sentences : Contain a single independent clause.
Example: She reads books.
Compound Sentences : Contain two or more independent clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon.
Example: She reads books, and she writes stories.

Syntax and Grammar Rules#
Word Order : English typically follows a Subject-Verb-Object (SVO) word order.
Example: She (S) reads (V) books (O).
Agreement : Subjects and verbs must agree in number (singular or plural).
Example: He reads (singular) vs. They read (plural).
