7.1 What Is a Conjunction?

One use of a conjunction is to connect words or phrases that have the same g rammatical structure in a sentence. This use of conjunctions is called Parallel Structure. The conjunctions used in this pattern are and, but, or, nor (more specifically called Coordinating Conjunctions).

Examples:

  • Noun + and + Noun
    Steve and his friend are coming to dinner.
  • Verb + and + Verb
    Susan raised her hand and snapped her fingers.
    He is waving his arms and (is) shouting at us.
  • In this case, the second auxiliary may be omitted if it is the same as the first.

  • Noun + and + Noun
    Steve and his friend are coming to dinner.
  • Adjective + but + Adjective
    These shoes are old but comfortable.
  • Infinitive + or + Infinitive
    He wants to watch TV or (to) listen to some music.
  • In this case the second to may be omitted.

    A parallel structure may contain more than two parts. In this case, commas are u sed to separate each unit. The final comma that precedes the conjunction is o ptional but is customarily used. No commas are used if there are only two parts to a parallel structure.

    Examples:

  • Steve, Joe, and Alice are coming to dinner.
    Susan raised her hand, snapped her fingers and asked a question.
    The colors in that fabric are red, gold, black and green.
  • Parallel structures make repeating the same words unnecessary.

            Exercise 1

    Combine the given sentences into one concise sentence that contains a parallel s tructure.

    Examples:

  • Mary opened the door. Mary greeted her guests.
    Mary opened the door and greeted her guests.
