Modifier Letter Low Acute Accent

Modifier Letter Low Acute Accent at U+02CF is a small spacing mark shaped like a low acute accent, used to write phonetic or linguistic modifiers as their own character rather than as a combining mark. It belongs to the Spacing Modifier Letters block, whose characters typically adjust or qualify nearby sounds in transcription systems. Its practical use is mainly in phonetics and language documentation, especially where a transcription needs a visible tone, stress, or prosodic sign that occupies its own position on the line. In specialized phonetic notation, marks like ˏ can appear after or near a syllable to show a low rising or low acute-type pitch contour, depending on the convention being used. It may also occur in digitized dictionaries, grammars, and archival linguistic data when older or custom transcription schemes are converted to Unicode. Because it resembles punctuation and accent marks but is neither a normal apostrophe nor a combining accent, searching or replacing it can require attention when cleaning copied linguistic text.
