Debuccalization Lenition Romance Japonic

Voiceless labiodental fricative to Voiceless glottal fricative

The debuccalization of the voiceless labiodental fricative /f/ to the glottal fricative /h/ is a classic example of lenition. This shift involves moving the site of friction from the lips and teeth to the glottis. It is famously documented in the transition from Latin to Spanish and also appears in the historical development of Japanese and other language families.
