Em Dash

Represented as a long horizontal line, the em dash is a versatile mark within the General Punctuation block. It is typically pronounced as "dash" or occasionally as "m-dash" to distinguish it from its shorter counterparts. Unlike the hyphen, this character is approximately the width of a capital letter M, serving as a distinct break in thought or a stylistic separation within a sentence.

Commonly found in professional typography and literature, this symbol functions as a replacement for commas, parentheses, or colons to add emphasis. In creative writing and journalism, it often signals an abrupt interruption in dialogue or sets off a parenthetical statement. It is also frequently used in digital social posts and academic papers to credit a quotation to a specific author at the end of a passage.
