Why is it "il la voit" and "il lui lit" (both, "la" and "lui", refering to "she")?
"Il la voit." = "He sees her." Here, "la" = "her" is the direct object of the verb "voir" = "to see."
"Il lui lit." = "He reads to her." Here, "lui" = "him/her" is the indirect object of the verb "lire" = "to read."
I guess this is more of an English language question, but why can't it be "He is seeing her in the magazine."?
Your sentence is not ungrammatical. The verb to see and other similar verbs are not commonly used in the present progressive, but there is no rule against it. Here is a link to an extensive discussion:
And here is a link to a Duolingo discussion page where I and others discuss the same issue:
I thought about both "is seeing" and "sees". They both felt awkward but I did pick "is seeing". Usually I'd say "he just saw". If this comes up again I'll try this since it feels like it's the best translation to English even though it's past tense. Update: "he just saw" is not accepted.
Does the ~ la~ here aggree with the gender or object? Can it mean both masc./fem. or does it have to mean -her? Thanks
The direct object pronoun "la" can mean "her" or "it." In either case, it is feminine and agrees with the gender of the direct object.
"He recognizes his sister when he sees her in the magazine." = "Il reconnaît sa sœur quand il la voit dans le magazine."
"He recognizes the house when he sees it in the magazine." = "Il reconnaît la maison quand il la voit dans le magazine."
My understanding is that when a phrase is a direct object you use le/la/les. But if it is an indirect object you use lui/leur. To clarify a direct object is the "person or thing that receives the action of a transitive verb" as is the case here. Whereas an indirect object is "the person or thing to/for whom the action of a verb is occurring." It is usually after a preposition, such as "à". For example, I gave a computer TO Jill. J'ai donné un ordinateur à Jill. In this case it would be Je lui ai donné.
I hear this sentence as "Il a voix dans le magazine" which means after me "He has voice (effect) in the magazine"
I heard, "Il avoir dans la magazine" ... which obviously doesn't make sense; my comprehension of spoken french is lame!
