Sentences

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).

Types of Sentences

Sentence Description Example
Declarative Makes a statement and ends with a period. - The sky is blue.
- The sky is not blue.
Interrogative Asks a question and ends with a question mark. - Do you like apples?
- Don’t you like apples?
Imperative Gives a command or makes a request and usually ends with a period. - Please close the door.
- Do not (don’t) close the door.
Exclamatory Expresses strong emotion and ends with an exclamation mark. - What a beautiful house!
- I can’t believe you did that!

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.
  • Complex Sentences: Contain one independent clause and at least one dependent clause.
    • Example: Although she was tired, she finished her homework.
  • Compound-Complex Sentences: Contain two or more independent clauses and at least one dependent clause.
    • Example: She finished her homework, and she went to bed after she was done.

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).
