|Sound change and alternation|
In phonology, epenthesis (/ -/,; Greek ἐπένθεσις) means the addition of one or more sounds to a word, especially in the beginning syllable (prothesis) or in the ending syllable (paragoge) or in-between two syllabic sounds in a word. The word epenthesis comes from epi- "in addition to" and en- "in" and thesis "putting". Epenthesis may be divided into two types: excrescence for the addition of a consonant, and for the addition of a vowel, svarabhakti (in Hindi, Bengali and other North Indian languages, stemming from Sanskrit) or alternatively anaptyxis (//). The opposite process, where one or more sounds are removed, is referred to as elision.
