Voiced uvular fricative to Mid central vowel

Language Examples

Coda [ʁ]→[ɐ/ə]— Standard vocalization of /r/ in word-final or preconsonantal positions (e.g., 'der' [deːɐ̯]).
Historical [ʁ]→[ə/ɐ]— Extensive reduction of the uvular rhotic in various phonetic environments, leading to its merger with existing central vowels.
