Empty sound / Zero to Voiced uvular fricative

The insertion of a voiced uvular fricative [ʁ] from an empty phonetic slot is a specific form of epenthesis or 'intrusive R'. In languages where the standard rhotic consonant is uvular (like modern French and German), this sound is sometimes inserted between two adjacent vowels to prevent a hiatus.

Language Examples

Il a eu [a_y]→Il a-r-eu [aʁy]— Informal or regional insertion of the uvular fricative to bridge the gap between two vowels.
wo ist [o_ɪ]→wo-r-ist [oʁɪst]— Similar to English intrusive R, some dialects insert a uvular fricative or tap to resolve hiatus.
