Diphthong ie to Close front unrounded vowel

The phonetic transformation from the diphthong 'ie' to the monophthong 'i' is a common process known as monophthongization. This involves the simplification of a two-part vowel sound into a single, unified vowel, often resulting in a lengthened version of one of the original diphthong components. This shift has occurred in various languages across different historical periods.

Language Examples

[iə]→[iː]— As part of the New High German monophthongization, starting in the 11th century, the diphthong 'ie' [iə] became a long monophthong [iː]. The spelling 'ie' was retained to represent the long 'i' sound.
⟨ie⟩→⟨i⟩— In Early West Saxon, the diphthong ⟨ie⟩ (possibly [iy] or [iə]) was often interchanged with ⟨i⟩ in writing, suggesting it was pronounced as a monophthong [i] during Alfred's time. This 'unstable ī̆' later corresponded to ȳ̆ in Late West Saxon. Monophthongization of ⟨ie⟩ to /i(ː)/ also occurred, particularly influenced by a following palatal consonant.
castiello→castillo— The diphthong 'ie' monophthongized to 'i' in certain contexts, such as before 'll'. This is noted as a 'weak' or 'minor, irregular' sound change in the declining phase of Old Spanish, sometimes influenced by palatal sounds.
cri(s)me (with 'ie')→cri(s)me (with 'i')— The reduction of 'ie' to 'i' is documented in various Old French dialects, including Walloon, Norman, and Picard.
