epenthesis: a process of inserting a sound, especially when this facilitates pronunciation. For example, in Nahuatl there is an epenthesis of the phoneme i between two initial consonants. (That is, Øflechai / #C__C.) Thus, since the base form /"k-neki"/ (it-want) 'he/she wants it' would be hard to pronounce, the word is pronounced /"kineki"/ instead. [Spanish: epéntesis]
