Alveolar lateral approximant to Voiceless labiodental fricative

The shift from the lateral approximant [l] to the voiceless labiodental fricative [f] is an extreme form of labialization and cluster merger. It typically occurs in word-final clusters where a vocalized lateral merges with an existing labial sound, or through developmental substitution in child language.
