General Category - Modifier Symbol
Modifier Symbol is a classification for characters that serve as small, often superscript or subscript, marks used to alter the meaning, sound, or pronunciation of an adjacent base character. These symbols do not typically combine with other characters in a visible, positional way, as spacing or nonspacing marks might, but instead stand as independent units while modifying the phonetic or semantic value of a word or syllable. Common examples include the gender symbols, the degree sign, and letters used as phonetic modifiers, such as the prime or the raised indicators in various linguistic notations. This category covers a wide range of typographic and orthographic tools, from marks indicating tonal shifts to symbols representing abbreviations, all of which function as compact, standalone adjustments to written language.
