In French there are several types of -ir verbs. The first type of regular -ir verbs add -iss- in the plural nous, vous and ils/elles forms. The second type omit the -iss- in the plural forms and can therefore be called irregular -ir verbs. In addition, the je, tu and il/elle forms end in -s, -s, -t rather than -is, -is, -it. Keep reading to discover the complete conjugations.
The verbs in the following table follow the standard pattern of irregular -ir verbs with the endings -s, -s, -t, -ons, -ez and -ent.
DORMIR TO SLEEP | SORTIR TO GO OUT | PARTIR TO LEAVE | COURIR TO RUN |
je dors tu dors il dort nous dormons vous dormez ils dorment j'ai dormi | je sors tu sors il sort nous sortons vous sortez ils sortent je suis sorti(e) | je pars tu pars il part nous partons vous partez ils partent je suis parti(e) | je cours tu cours il court nous courons vous courez ils courent j'ai couru |
SENTIR TO SMELL | MENTIR TO LIE | MOURIR TO DIE | SERVIR TO SERVE |
je sens tu sens il sent nous sentons vous sentez ils sentent j'ai senti | je mens tu mens il ment nous mentons vous mentez ils mentent j'ai menti | je meurs tu meurs il meurt nous mourons vous mourez ils meurent il/elle est mort(e) | je sers tu sers il sert nous servons vous servez ils servent j'ai servi |
The second kind of irregular -ir verbs end in -rir in the infinitive and have the same endings as regular -er verbs: -e, -es, -e, -ons, -ez, -ent. To form the past participle with these verbs, take the -rir off of the infinitive and replace it with -ert.
COUVRIR TO COVER | DÉCOUVRIR TO DISCOVER | OFFRIR TO OFFER | SOUFFRIR TO SUFFER |
je couvre tu couvres il couvre nous couvrons vous couvrez ils couvrent j'ai couvert | je découvre tu découvres il découvre nous découvrons vous découvrez ils découvrent j'ai découvert | j'offre tu offres il offre nous offrons vous offrez ils offrent j'ai offert | je souffre tu souffres il souffre nous souffrons vous souffrez ils souffrent j'ai souffert |
