Difference Between Colon and Semicolon

Colons and semicolons are both used to indicate a relationship between two ideas, but the relationship indicated by these two punctuation marks is different. That is to say, the functions of these two punctuation marks are vastly different. Colons are used to introduce a list of items, expansion or explanation or a quotation whereas semicolons are used to separate major elements of a sentence. This is the main difference between colon and semicolon. We’ll discuss these different functions of colons and semicolons in this article.

What is a Colon

Colon (:) is a punctuation mark that is mainly used to introduce something. A colon is typically used after an independent clause. There are three main uses of colons. It can be used after an independent clause when the second clause explains the first (independent) clause. The second clause can be a definition, explanation, summary of the first.

What is a Semicolon

A semicolon (;) looks like a comma with a period over it. The main function of a semicolon is to create a break that is stronger than a comma, but not as strong as a full stop.
