What ᪱ means
It modifies a vowel in Teuthonista transcription.
The documented Teuthonista spelling a᪱ corresponds to ɶ in the International Phonetic Alphabet, a standard set of speech-sound symbols. Teuthonista, also called Böhmer-Ascoli, records spoken sounds, especially Romance and Germanic dialects.
It is a phonetic mark, not an ordinary umlaut or ring; different Teuthonista versions can assign shared marks different values, so the transcription key settles its reading.
How did Teuthonista develop?
Its notation grew through several related systems.
Lepsius’s general phonetic alphabet appeared in 1855; Ascoli’s Romance transcription followed in 1873, and Böhmer published vowel marks in 1880. Lenz’s system was developed by 1900; Teuchert adapted it for the Teuthonista journal in 1924/25, whose name the notation adopted.
