Old Irish

Etymology

From Proto-Celtic *demenis (“certain”), of disputed origin. MacBain derives it from Proto-Indo-European *dʰh₁men- (“that which is established”), while Pedersen derives it from Proto-Celtic *dī- + a derivative of Proto-Indo-European *men- (“to change”), thus ‘unchangeable’.

Pronunciation

• IPA^(key): [ˈdʲeβ̃ʲinʲ]

Adjective

demin (equative demnithir, comparative demniu)

1. sure, certain

     What we see with (lit. from) the eyes is more certain to us than what we hear with (lit. from) the ears.
