What Deputy Colon teaches

Deputy Colon handles introducing lists after a statement, clarifying a preceding statement, time (3:10), titles and subtitles, word groups.

Deputy Colon teaches the same idea across every grade, starting simple and going deep. Here is the whole concept: what it does, the jobs and kinds it splits into, the mistakes to watch for, and a worked example for each.

Deputy Colon at work

Deputy Colon announces what comes next: a list, an explanation, or a payoff, and everything after him delivers on the promise. He packed three things: rope, water, and a map. Where Sheriff Semicolon balances two equal halves, the Colon points forward, telling you the answer is right behind him.

Meet Sheriff Semicolon.

Concept
Introduce lists

Use a colon to introduce a list, especially after 'as follows' or when the colon stands alone after an independent clause.

Examples
  • "I invited the following guests to the party: Jake, Nelson, Izzy, Benny, and Connie."
  • "Some of the major spoken languages of Nigeria are as follows: Hausa, Igbo, Yoruba, and Ibibio."
  • "For dessert, Spencer chose from his favorites: cookies, ice cream, fruit, and pudding."
Watch out for
  • Using colon before a list in the middle of a sentence
  • Missing colon before list after independent clause
  • Using colon before dependent clause
Concept
Introduce clarifying statements or explanations

Use a colon to introduce a statement that clarifies, explains, or expands upon what came before.

Examples
  • "The meeting had one purpose: to discuss the budget."
  • "She had accomplished her goal: winning the competition."
  • "The answer is simple: practice makes perfect."
Watch out for
  • Using comma instead of colon
  • Capitalizing the word after colon when it's not a proper noun (inconsistent)
  • Using colon before a dependent clause
