demin

From Proto-Celtic *demenis (“certain”), of disputed origin. MacBain derives it from Proto-Indo-European *dʰéh₁mn̥ (“that which is established”), while Pedersen derives it from Proto-Celtic *dī- + a derivative of Proto-Indo-European *men- (“to change”), thus ‘unchangeable’.

• IPA^(key): /ˈdʲeṽʲinʲ/
