Cyrillic modifier small e

It marks a sound detail; the notation key supplies its value.

Superscript transcription records speech details that ordinary spelling leaves out. A Serbian dialect study from 1905 uses raised and lowered letters to distinguish vowel strength; a Russian pronunciation dictionary from 1989 uses raised э for a fleeting vowel after a consonant changes to match its neighbor.

In Chuvash, a language written in Cyrillic, и𞁈 marks a lower-sounding version of the vowel и. The notation key matters: the same raised letter can signal different details.
