## 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: [ˈdʲeβ̃ʲinʲ]

### Adjective

demin (equative demnithir, comparative demniu)
* sure, certain
