Voiceless alveolar fricative to Alveolar lateral approximant

The transformation of the voiceless alveolar fricative /s/ to the alveolar lateral approximant /l/ is a documented phonetic shift, often involving processes of lenition, voicing, and lateralization. This change sees the turbulent, central airflow of the fricative replaced by the laminar, lateral airflow of the approximant, frequently occurring in specific phonological environments or across language families over time.
