Hyphen

Represented as a short horizontal stroke, the hyphen is a foundational mark within the General Punctuation block. It is primarily used to connect words or parts of words, functioning as a grammatical link rather than a subtraction symbol or a long dash. While it appears nearly identical to the hyphen-minus found on standard keyboards, this specific character is the typographically correct version intended purely for linguistic purposes. In speech, it is not typically vocalized, though it indicates a specific relationship between the terms it joins.

Common applications of this mark are found in formal typography and professional publishing to manage compound modifiers and word breaks. It appears frequently in compound adjectives, such as middle-class or well-known, and is used to separate syllables when a word reaches the end of a line of text. Additionally, it serves a functional role in writing phone numbers or social security digits, providing visual clarity by grouping numerical sequences into readable segments.
