Prothesis (linguistics)

In linguistics, prothesis (/ˈprɒθɪsɪs/; from post-classical Latin[1] based on Ancient Greek: πρόθεσις próthesis 'placing before'),[2][3] or less commonly[4] prosthesis (from Ancient Greek πρόσθεσις prósthesis 'addition')[5][6] is the addition of a sound or syllable at the beginning of a word without changing the word's meaning or the rest of its structure. A vowel or consonant added by prothesis is called prothetic or less commonly prosthetic.

Prothesis is different from the adding of a prefix, which changes the meaning of a word.

Prothesis is a metaplasm, a change in spelling or pronunciation. The opposite process, the loss of a sound from the beginning of a word, is called apheresis or aphesis.
