Semicolons, colons and commas: review

Key Notes:

  • Purpose: Semicolons are used to link closely related independent clauses (complete sentences) without using a conjunction (like “and” or “but”).
  • Example: I have a big test tomorrow; I need to study tonight.
  • Used with Transitional Phrases: Semicolons are also used before words or phrases like however, therefore, for example, in addition, etc., when connecting two independent clauses.
  • Example: I wanted to go to the beach; however, it started to rain.

  • Purpose: A colon is used to introduce a list, explanation, or quote.
  • Lists: Use a colon to introduce a list when the clause before the colon is a complete sentence.
  • Example: Please bring the following items to class: pencils, notebooks, and a calculator.
  • Explanation/Clarification: A colon is also used to introduce an explanation or elaboration of what was mentioned before it.
  • Example: She had one goal in mind: to become a famous artist.
  • Before a Quote: Colons can introduce direct quotes.
  • Example: He said: “I will finish my homework tonight.”

  • Purpose: Commas are the most commonly used punctuation mark, helping to separate elements within a sentence to clarify meaning.
  • Separating Items in a List: Commas are used to separate items in a series or list.
  • Example: I bought apples, oranges, bananas, and grapes.
  • Before Coordinating Conjunctions: Commas are used before conjunctions like and, but, or, nor, for, yet, and so when they join independent clauses.
  • Example: I wanted to go swimming, but it was too cold.
  • After Introductory Elements: A comma is used after introductory words, phrases, or clauses.
  • Example: After the meeting, we went to lunch.
  • With Nonessential Information: Use commas to set off nonessential information or clauses that don’t change the meaning of the sentence.
  • Example: My brother, who lives in New York, is visiting us next week.

  • Semicolons connect closely related independent clauses or separate items in complex lists.
  • Colons introduce lists, explanations, or quotes.
  • Commas separate elements within sentences to enhance clarity, such as in lists, after introductory phrases, or to set off nonessential information.
