Bonjour est ce que would est un verbe irrégulier ? (Prétérit simple)

Non var la conjugaison de would au passé simple est :
I would, you would, he would, we would, you would;
, they would.
 
Would est l'auxiliaire du conditionnel. ex: If it were fine, we would go on a picnic. S' il faisait beau, nous irions pique-niquer.
