Voiced labio-velar approximant to Voiced palatal approximant

The transformation of the voiced labio-velar approximant /w/ to the voiced palatal approximant /j/ is an attested phonetic shift, often occurring in specific phonological environments. This change involves a shift in the place of articulation from the labio-velar region to the palatal region, effectively fronting the articulation of the glide.

Fronting, Palatalization

Language Examples

/-iwope/→/-ijope/— Proto-Mojeño-Trinitario *-iwope 'sole of the foot' became -ijope in Trinitario. This shift occurs regularly when /w/ precedes /p/.
/wa/→/ja/— In the eastern part of the Modern West Frisian language area, rising diphthongs with initial /w/, such as /wa/, are pronounced as [ja].
/wo/→/jo/— In the eastern part of the Modern West Frisian language area, rising diphthongs with initial /w/, such as /wo/, are pronounced as [jo].
