hydrogéner
hydrogéner
French
Verb
hydrogéner
- (transitive, chemistry) to hydrogenate
Conjugation
This verb is conjugated like céder. It is a regular -er verb, except that its last stem vowel alternates between /e/ (written ‘é’) and /ɛ/ (written ‘è’), with the latter being used before mute ‘e’. One special case is the future stem, used in the future and the conditional. Before 1990, the future stem of such verbs was written hydrogéner-, reflecting the historic pronunciation /e/. In 1990, the French Academy recommended that it be written hydrogèner-, reflecting the now common pronunciation /ɛ/, thereby making this distinction consistent throughout the conjugation (and also matching in this regard the conjugations of verbs like lever and jeter). Both spellings are in use today, and both are therefore given here.
