The semicolon ; is a symbol commonly used as orthographic punctuation. In the English language, a semicolon is most commonly used to link two independent clauses that are closely related in thought, such as when restating the preceding idea with a different expression. When a semicolon joins two or more ideas in one sentence, those ideas are then given equal rank. Semicolons can also be used in place of commas to separate items in a list, particularly when the elements of the list themselves have embedded commas.

The question mark ? is a punctuation mark that indicates a question or interrogative clause or phrase in many languages.
