error when conjugating a verb "found"

[BryanKoo]

Conjugating a verb "found" is not working properly. The result is the same as conjugating a verb "find". lexeme('found') also gives the same result as find. ['find', 'finds', 'finding', 'found'] The result should be ['found', 'founds', 'founding', 'founded'] It seems that conjugate(lexeme) function is designed to work with all conjugated forms of a verb for convenience.

I think there should be an input option that specifies whether the input verb is in infinitive form or not.

Though different from the above problem, I have found wrong or incomplete conjugations with verbs: address,barbeque,bear,bind,bite,coach,daydream,dream,escape,feed,grip,lay,lean,leave,live,light,may,number,pay,plead,ring,sing,sank,sneak,spoil,spring,summon. I think NLP AI should be combination of rule-based and machine learning for higher accuracy.
