There are three regular verb groups in French: the ones that end in the infinitive form -ER, the ones that end -RE and finally the ones that end -IR.
This is about the -IR-group of verbs.

How to form all the six forms of IR-verbs? Listen to the video.



FINIR

je finis  nous finissons
tu finis  vous finissez
il/elle finit  ils/elles finissent

Other verbs of the same group:

choisir = to choose
réfléchir = to think
réussir = to succeed
maigrir = to lose weight
grossir = to put on / gain weight
viellir = to get old
