Clauses are the building blocks of sentences, forming the foundation of clear communication. Independent clauses stand alone, while dependent clauses rely on others to complete their meaning. Understanding these distinctions is crucial for crafting effective sentences.

Conjunctions play a vital role in connecting clauses and creating more complex sentence structures. Coordinating conjunctions join equal elements, while subordinating conjunctions introduce dependent clauses. Mastering these connectors enhances your ability to express complex ideas clearly.

Clauses

Types of Clauses and Their Functions

  • Independent clause expresses a complete thought and can stand alone as a sentence
    • Contains a subject and a predicate
    • Functions as the core of a sentence (The sun shines brightly)
    • Can be joined with other independent clauses to form compound sentences
  • Dependent clause cannot stand alone as a complete sentence
    • Relies on an independent clause to form a complete thought
    • Often begins with a subordinating conjunction or relative pronoun
    • Adds additional information to the main clause (When the sun shines)
  • Subordinate clause serves as a dependent clause in a sentence
    • Provides supplementary information to the main clause
    • Can function as a noun, adjective, or adverb in a sentence
    • Enhances the meaning of the independent clause (because it was raining)
  • Main clause acts as the independent clause in a complex sentence
    • Carries the primary message of the sentence
    • Can stand alone grammatically and semantically
    • Supports dependent clauses to create more complex sentence structures (I stayed home)

Identifying and Using Clauses

  • Independent clauses identified by their ability to stand alone
    • Test by separating the clause and checking if it forms a complete sentence
    • Can be connected using coordinating conjunctions (and, but, or)
  • Dependent clauses recognized by their inability to form complete thoughts
    • Often begin with subordinating conjunctions (although, because, while)
    • Require attachment to independent clauses for completeness
  • Subordinate clauses categorized based on their function in a sentence
    • Noun clauses act as subjects, objects, or complements (What he said surprised me)
    • Adjective clauses modify nouns or pronouns (The book that I read was fascinating)
    • Adverb clauses modify verbs, adjectives, or other adverbs (She smiled when she saw him)
  • Main clauses identified as the essential part of a sentence
    • Contain the primary subject and verb of a complex sentence
    • Can be found by removing all dependent clauses from a sentence

Conjunctions

Coordinating Conjunctions and Their Uses

  • Coordinating conjunctions connect words, phrases, or clauses of equal grammatical rank
    • Remembered using the acronym FANBOYS (For, And, Nor, But, Or, Yet, So)
    • Join independent clauses to form compound sentences (I like coffee, and I enjoy tea)
    • Used to connect items in a list or series (apples, oranges, and bananas)
  • For indicates a reason or purpose
    • Links two related independent clauses (I was tired, for I had worked all night)
  • And adds information or ideas
    • Joins similar elements in a sentence (She sang and danced)
  • Nor connects two negative ideas
    • Used in pairs to express alternatives (Neither the car nor the bike was available)
  • But introduces a contrast or exception
    • Shows opposition between ideas (He tried hard but failed)
  • Or presents alternatives or choices
    • Offers options in a sentence (Would you like coffee or tea?)
  • Yet expresses a contrast or unexpected result
    • Similar to "but" with a stronger emphasis (He studied hard, yet he failed the exam)
  • So indicates a result or consequence
    • Shows cause and effect relationships (It was raining, so we stayed indoors)

Subordinating Conjunctions and Complex Sentences

  • Subordinating conjunctions introduce dependent clauses
    • Connect dependent clauses to independent clauses
    • Include words like after, although, as, because, before, if, since, when, while
  • Subordinating conjunctions indicate various relationships between clauses
    • Time relationships (after, before, when, while, until)
    • Cause and effect (because, since, as)
    • Condition (if, unless, provided that)
    • Contrast (although, though, even though)
  • Placement of subordinating conjunctions affects sentence structure
    • Can appear at the beginning of a sentence (Because it was raining, we stayed home)
    • Can appear in the middle of a sentence (We stayed home because it was raining)
  • Subordinating conjunctions create complex sentences
    • Combine one independent clause with one or more dependent clauses
    • Enhance the complexity and depth of written expression

Sentence Types

Compound Sentences: Structure and Usage

  • Compound sentences consist of two or more independent clauses
    • Joined by coordinating conjunctions, semicolons, or conjunctive adverbs
    • Each clause can stand alone as a complete sentence
  • Coordinating conjunctions in compound sentences
    • Use FANBOYS to connect independent clauses (I love reading, and I enjoy writing)
    • Require a comma before the coordinating conjunction
  • Semicolons in compound sentences
    • Join closely related independent clauses without a conjunction (I love reading; I enjoy writing)
    • Can be used with conjunctive adverbs (I love reading; however, I enjoy writing more)
  • Compound sentences add variety to writing
    • Allow for the expression of related ideas in a single sentence
    • Help to show relationships between thoughts or actions

Complex Sentences: Components and Formation

  • Complex sentences contain one independent clause and at least one dependent clause
    • Dependent clause cannot stand alone as a complete thought
    • Independent clause forms the main idea of the sentence
  • Subordinating conjunctions introduce dependent clauses in complex sentences
    • Connect the dependent clause to the independent clause
    • Indicate the relationship between the two clauses (When it rains, the plants grow)
  • Relative pronouns can also introduce dependent clauses
    • Include who, whom, whose, which, and that
    • Form relative clauses that modify nouns or pronouns (The book that I read was interesting)
  • Order of clauses in complex sentences can vary
    • Dependent clause can come before the independent clause (While I was sleeping, the phone rang)
    • Independent clause can come first, followed by the dependent clause (The phone rang while I was sleeping)
  • Complex sentences add depth and nuance to writing
    • Allow for the expression of more sophisticated relationships between ideas
    • Enhance the flow and coherence of written communication
