Diphthong ie to Nasalized close-mid front unrounded vowel
The diphthong /ie/ can undergo a transformation to the nasalized close-mid front unrounded vowel /ɛ̃/ through a process involving both monophthongization and nasalization. This shift is notably observed in the historical development of French, where oral diphthongs in certain contexts evolved into nasalized monophthongs.

Language Examples
bien→bien— The Latin short /e/ in 'bene' diphthongized to /ie/ in Old French. Subsequently, this diphthong became nasalized due to a following nasal consonant, and then underwent monophthongization and lowering, resulting in the modern French nasalized vowel /ɛ̃/ (often with a preceding /j/ glide).
