Object pronouns

Direct or indirect is not about meaning, it is about what the verb takes. Voir, aimer and attendre take a direct object, so je le vois. Parler, donner, dire and téléphoner take à, so je lui parle. Je lui vois is the error, and the cure is learning each verb with its preposition attached.

Je vois Marie, but je la vois: the pronoun jumps in front of the verb, the opposite of English. Le, la and les replace a noun with no preposition, and me, te, le and la shorten before a vowel: je t'aime. Je vois le is the error to unlearn.

With a verb plus an infinitive, the pronoun goes before the infinitive, the verb it belongs to: je vais le voir, tu peux lui parler. With two pronouns, le, la and les come first and lui and leur second: je le lui donne.
