Close-mid front unrounded vowel to Voiced palatal approximant

The transformation from the close-mid front unrounded vowel /e/ to the voiced palatal approximant /j/ is a common phonetic process known as vocalization or glide formation. This shift often occurs when the vowel /e/ is in a weak position, such as in a hiatus sequence or an unstressed syllable, leading to its reduction and approximation towards a palatal glide. This process is a form of diphthongization, where a monophthongal vowel develops a glide component.
