This paper examines historical changes affecting coda laterals in British English, in the light of findings from articulatory phonology, with some insights from acoustic and perceptual phonetics as well. Historically, coda laterals induce pre-lateral diphthongisation and are themselves vocalised/lost, usually to a back rounded vowel. Coda laterals involve a radical gesture (retracted tongue root), and diphthongisation is caused by a gestural conflict between the laminal-dorsal gesture of the vowel and the radical gesture of the following lateral, producing an excrescent vowel in the transition. This excrescent vowel sounds like a schwa or /ɔ/ due to a shared post-oral gesture between these vowels and coda laterals. Vocalisation/loss is caused by gestural reduction, whether in terms of time, timing or space.
