Voiceless postalveolar fricative to Voiced palatal approximant

The shift from the voiceless postalveolar fricative [ʃ] (sh) to the palatal approximant [j] is a process of gliding or lenition. This weakening occurs when the turbulent airflow of the fricative is smoothed into a sonorous glide, typically passing through an intermediate palatal fricative [ç] stage.

Language Examples

historical /ʃ/→[j]— In some Gulf or Levantine dialects, sibilant fricatives can weaken toward palatal glides in specific phonetic environments.
/ʃ/ (coda)→[j]— In some varieties, the coda sibilant [ʃ] can reduce to a light palatal glide before certain consonants.
