I have found it impossible to learn the 2 conjugations of this verb. I am probably way worse at rote memorization than most other people (and not just for French). Every so often I come back to it here, hoping something will strike me. Aha! I just noticed that the endings for the first conjugation present indicative are the same as for voir! Small progress. As for the second conjugation, are there any "familiar" verbs that have these endings? I tried to used Ez-glot to find similar endings, but the site is no longer accessible.
Thanks
