I need help with y, en, le, lui. I keep missing these in the quiz

Hi Bill,

As for when to use the direct object pronoun 'le' or the indirect object pronoun 'lui', you will need to study the following lessons -

Using lui/leur = him or her/them (French Indirect Object Pronouns)

Using le/la/l'/les = it/him/her/them (French Direct Object Pronouns)

Hope this is helpful!
