Suffix

-ir

1. (non-productive) forms the infinitives of many verbs

Usage notes

• 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; some such examples are finir (“to finish”), nourrir (“to feed, to nourish”), accomplir (“to accomplish”), and polir (“to polish”).
• Many verbs with infinitives in -ir have an inchoative meaning. Examples include blanchir (“to whiten, to bleach, to make whiter, to become pale”), durcir (“to harden, to make more rigid, to become stronger”), grandir (“to become bigger, to magnify, to make bigger”), rougir (“to redden, to blush, to become redder, to make redder”), and vieillir (“to age, to become older, to make older”).
• 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”) (but these examples are also irregular, with sors instead of *sortis). An irregular -ir verb which is truly conjugated exactly as a regular -ir verb except only without the infix (although it is dated and has a regular alternative conjugation) is chauvir.
• 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”), and the verb bruire.
• 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.

Conjugation

This is a regular verb of the second conjugation, like finir, choisir, and most other verbs with infinitives ending in -ir. One salient feature of this conjugation is the repeated appearance of the infix -iss-.
