Practicing Verbs not preceded by an indirect object Hi I want to practice the certain french verbs that are not preceded by an indirect object. To replace a person I must keep the preposition and replace the person with demonstrative pronoun. To replace a thing or an idea I can use y, which replaces to both but is placed before the verb. Please correct the following and explain your reasoning if any of my sentences are wrong; Je crois toi -. I believe you, not je te crois. Although I've heard je te crois before, is it an option? J'y crois - I believe it. Je crois a toi - I believe in you J'ai cru ils. - I believed them. Il a cru elle. - He believed her. Il y a ete penser - He had been thinking about it ils y avaient pense - They had thought about it ils y pensaient - They were thinking about it.
