Catalan third conjugation (-ir) verbs with an infixed -eix- in root-stressed forms.

These verbs are technically known as inchoatives based on the corresponding class in Latin, although they no longer have an inchoative meaning. The forms with -eix- are those where the stress would otherwise fall on the verb root, i.e. the whole singular and the third-person plural of the present indicative and subjunctive, as well as the second-person singular imperative. The majority of third conjugation verbs, including all newly-coined verbs of this conjugation, take an -eix- infix. See also Category:Catalan third conjugation verbs without -eix-.
