U+1D9F "ᶟ" Modifier Letter Small Reversed Open E Unicode Character

Unicode Version 17.0

U+1D9F "ᶟ" Modifier Letter Small Reversed Open E is a diacritical mark used in phonetic transcription, specifically within the International Phonetic Alphabet and its extended notations, to modify the sound of a preceding or following letter by indicating a specific vowel quality or articulatory nuance. It represents a small, reversed version of the open e vowel, which in standard IPA denotes a near-open front unrounded vowel, but its reversed orientation in this modifier form can signal a change in the vowel's backness or rounding. This character is primarily employed in scholarly linguistic work to capture subtle pronunciation distinctions that are not covered by basic vowel letters, making it a specialized tool for precision in phonetic documentation and language analysis.
