U+02D7 "˗" Modifier Letter Minus Sign Unicode Character

U+02D7 "˗" Modifier Letter Minus Sign is a typographic symbol used in phonetic transcription and orthography to indicate a negative or lowered tone, often appearing in linguistic notations such as the International Phonetic Alphabet or in certain romanization systems. Its visual form resembles a horizontal bar similar to a hyphen but is positioned at the height of a modifier letter, intended to modify the meaning of an adjacent character. Unlike the standard minus sign or hyphen, this glyph belongs to the category of spacing modifier letters that alter the semantic or phonetic value of a preceding letter without being a full punctuation mark. It is thus employed primarily in specialized writing systems to convey specific tonal distinctions or to mark a subtractive morpheme, rather than for arithmetic or general punctuation purposes.
