This verb follows the so-called regular -er verb pattern, the pattern followed by vast majority of verbs of the language, and by practically all new verbs entering the language.

The regular -er pattern has the following defining features:

• No characteristic consonant (contrast, for example, with verbs following the finir or dormir patterns, which have a characteristic -ss- and -m- in all forms but the present tense singular);
• No vowel change in the stem, other than where necessary to respect general patterns of French phonology (e.g. see préférer)²;
• Past participle in -é¹.

1. Outside the regular -er paradigm, only aller, être and naître have past participles ending in -é.
2. Many other verb patterns, except verbs of the finir type plus a few other patterns, have an irregular vowel change, e.g. boire > je bois vs nous buvons. See the grammar section on irregular verb patterns in French for a list of the different vowel changes.
