Types of Phrases

    • Often contain an adverb and its modifiers, such as other adverbs or prepositional phrases

    • Past participle phrases use the -ed form of regular verbs or the irregular past participle form
  • Gerund phrases use the -ing form of a verb and function as nouns (swimming in the ocean)
    • Can serve as the subject, object, or complement of a sentence
    • Often accompanied by modifiers or objects

Clause Basics

  • A clause is a group of words containing a subject and a predicate, forming a simple sentence or part of a compound or complex sentence
  • The subject of a clause is the person, place, thing, or idea that the clause is about (The curious child)
  • The predicate of a clause tells us something about the subject, such as an action or state of being (explored the garden)
  • Clauses can be classified as independent or dependent based on their ability to stand alone as complete sentences
  • Independent clauses, also known as main clauses, express a complete thought and can function as a sentence on their own (She loves to read books)
  • Dependent clauses, also known as subordinate clauses, do not express a complete thought and depend on an independent clause to form a complete sentence (because he arrived late)
  • Clauses can be joined using coordinating conjunctions (and, but, or) to form compound sentences or subordinating conjunctions (although, if, when) to form complex sentences

Independent vs. Dependent Clauses

  • Independent clauses contain a subject and a predicate and can stand alone as complete sentences (The sun was shining brightly)
    • Express a complete thought and do not depend on another clause to convey meaning
    • Can be joined with other independent clauses using coordinating conjunctions (and, but, or) to form compound sentences
  • Dependent clauses also contain a subject and a predicate but cannot stand alone as complete sentences (which was covered in snow)
    • Do not express a complete thought and depend on an independent clause to convey meaning
    • Often begin with subordinating conjunctions (although, because, if) or relative pronouns (who, which, that)
    • Function as adjectives, adverbs, or nouns within a sentence
  • Adjective clauses, also known as relative clauses, modify nouns or pronouns (The book that I borrowed from the library)
    • Begin with relative pronouns (who, which, that) or relative adverbs (where, when)
    • Provide additional information about the noun or pronoun they modify
  • Adverb clauses modify verbs, adjectives, or other adverbs (She will attend the conference if she can get time off work)
    • Begin with subordinating conjunctions (although, because, if)
    • Provide information about time, place, manner, condition, or reason
  • Noun clauses function as the subject, object, or complement of a sentence (What he said surprised everyone)
    • Begin with words like what, who, which, that, or how
    • Can be replaced by a noun or pronoun without changing the meaning of the sentence

Putting It All Together

  • Effective use of phrases and clauses allows for more varied and interesting sentence structures
  • Simple sentences contain one independent clause and no dependent clauses (The dog barked)
    • Convey a single idea or thought
    • Can be used for emphasis or to create a straightforward tone
  • Compound sentences consist of two or more independent clauses joined by a coordinating conjunction or semicolon (The cat meowed, and the bird chirped)
    • Express multiple related ideas or thoughts
    • Coordinating conjunctions (and, but, or) show the relationship between the clauses
  • Complex sentences contain one independent clause and one or more dependent clauses (Although it was raining, she decided to go for a walk)
    • Subordinating conjunctions (although, because, if) or relative pronouns (who, which, that) connect the dependent clause to the independent clause
    • Dependent clauses provide additional information or context for the main idea expressed in the independent clause
  • Compound-complex sentences have two or more independent clauses and one or more dependent clauses (She enjoyed the movie, but her friend, who prefers action films, found it boring)
    • Combine the features of both compound and complex sentences
    • Allow for expressing multiple ideas and their relationships in a single sentence
  • Varying sentence structure by using different types of phrases and clauses enhances the flow and rhythm of writing
  • Proper punctuation, such as commas and semicolons, helps clarify the relationships between phrases and clauses within a sentence

Common Mistakes to Avoid

  • Sentence fragments occur when a dependent clause or phrase is punctuated as a complete sentence (Because he was tired)
    • To fix, either attach the fragment to an independent clause or rewrite it as a complete sentence
  • Run-on sentences happen when two or more independent clauses are joined without proper punctuation or conjunctions (She loves to sing she performs in a choir)
    • To correct, use a period to separate the clauses into individual sentences, add a coordinating conjunction, or use a semicolon
  • Misplaced or dangling modifiers occur when a phrase or clause is not clearly connected to the word it modifies (Walking through the park, the flowers were in bloom)
    • To resolve, place the modifier close to the word it describes or rewrite the sentence to clarify the relationship
  • Overuse of passive voice can make writing less engaging and harder to understand (The ball was thrown by the boy)
    • To improve, use active voice when possible (The boy threw the ball)
  • Lack of parallel structure occurs when elements in a series or list do not follow the same grammatical pattern (She likes to read, write, and painting)
    • To maintain consistency, ensure that all elements in a series or list have the same grammatical form (She likes to read, write, and paint)
  • Unclear pronoun references happen when it's not clear which noun a pronoun refers to (John told Mike he would be late)
    • To avoid confusion, use specific nouns or rephrase the sentence to clarify the pronoun reference

Practice Makes Perfect

  • Analyze sentences in reading materials to identify different types of phrases and clauses and their functions
  • Construct sentences using various types of phrases and clauses to express ideas in different ways
