French[edit]

Etymology[edit]

From Latin -īre, the ending of the present active infinitive form of fourth conjugation verbs. Cognate with Spanish -ir, Italian -ire, Romanian -i and , etc.

Suffix[edit]

-ir

  1. A suffix forming infinitives of many verbs.

Usage notes[edit]

  • Most verbs with infinitives in -ir are marked by the once-inchoative infix -iss- in many parts of their conjugation, as well as in various derived words; two such verbs are choisir (to choose) and pourrir (to rot). A fair number of these have English counterparts in -ish; three such are finir (to finish), nourrir (to feed, to nourish), and polir (to polish).
  • A sizable group of verbs have infinitives in -ir but do not use the infix -iss-, and are otherwise fairly regular; these include, among others, the common verbs sortir (to go out, to take out), partir (to leave), dormir (to sleep).
  • This suffix is spelled -ïr on a few verbs where the previous syllable ends in a vowel, such as haïr (to hate) and ouïr (to hear). Additionally, it is spelled -ire on the verb maudire (to curse), by analogy with the related but irregular verb dire (to say).
  • Not all verbs whose infinitives happen to end in these letters can truly be said to have this suffix; in particular, a fair number of irregular verbs have infinitives in the unrelated suffix -oir.
