Colon is one of the punctuation which is used to:

1. Lay emphasis

Example: He loved just one: Bruno, his dog

2. To present dialogue ( we write the name of the speaker and then insert colon followed by his/her dialogue.)

Example: Rita: How are you?

Mary: Fine, and you?

3. Clarify composition titles ( to explain parallel ideas colon is used in compositions like lectures or book titles), and

Example: Rousseau’s Dog: Two Great Thinkers at War in the Age of Enlightenment

4. To introduce text or lists.

Example: Three types of Subordinate or Dependent Clauses are: Adjective clause, Adverb clause and Noun clause
