"Mi padre no las conoce."
How can "las" be translated as "you" in this case without there being "ustedes?"
The translation is not correct, 'My father does not know THEM.' The formal you is 'les'
It's not using usted "formal you" though, it's using the ustedes "you all," right?
Another incorrect post (gro-com's). The translation is correct, but would be clearer if it were "you all" and not "you" "Les" should never be used as a direct object pronoun, it is only proper as an indirect object pronoun.
Yes, you are correct Kevin - the "las" in this sentence could mean them, or plural you -Ustedes. This is the direct object pronoun, and is can be used for both third person plural or second person plural.
"Les", however, would not be correct in this sentence since it is an indirect object pronoun.
This is a stretch using "las=you". I can see that it might be correct, but it implies that there is more than one of you, which is not indicated.
Both "you" and "them" are correct translations; which is meant would be indicated by context. In the case of "you", this context might be a girl talking to two other girls. Often Spanish translations are ambiguous without context, and Duolingo accepts any of the possible correct translations.
It could either "Mi padre no conoce a ellas" or "Mi padre no las conoce" - but both sounds a bit redundant...
I think I'm a bit (or a lot) confused about when this double reference (seemingly indeed redundant) to a person is accepted and when it's not...
The "las" is needed as it is the direct object and the sentence without it would read "Mi padre no conoce." As you can see, without the "las' it does not identify "who" he does not know.
Now that I got it wrong I see why their translation is correct. However without context I think it is silly to put a "you" in there like this. The logical jump is to think it means 'them', which was not an option for me to pick.
No, but this is an indirect pronoun meaning plural female. It doesn't actually MEAN them or you, exactly. It is in place of saying (them - the women, or my female friends, or whatever) or (you - all you females in front of me),,,,,
I think you meant: It is a direct object pronoun. (DO = los & las, IO=les)
