I would argue that "their" works well here actually, because (at least in my experience) when referring to something that belongs to someone else (like a face) when you don't know the gender of that person, many people will use "their" instead of "his" or "her" even when referring to just one person.
Can this also translate to "do you remember their faces?" and "do you remember your faces?" (let's say in a hypothetical situation where a group of people vowed never to look in a mirror).
I remember several lessons ago someone pointed out that when referring to multiple people's faces (or other singular body parts), you'd still use the singular form for the object, since each person only has one face.
No, that wouldn't really work here. It (likely, there might be another mechanism where that idea works, too) has to do something with whether you're using a reflexive/objective form of the verb or not. If you use the objective form (something like "Le miré la cara" - "I looked him in the face"), the pronoun already specifies which individual you're considering, so you'll only talk about the body parts of that person. Meaning, if you use the se/te/le/etc. form of the verb, you'll only talk about one face, one mouth, one body, two hands, two ears, and so on, anything that is part of one single person. If you don't use that objective form, you're talking about the collective body parts of all people you include.
- Les besó la boca. - She kissed them on the mouth.
- Besó sus bocas. - She kissed their mouths.
The objective form doesn't function like that with recordar (presumably because you don't actually do something to those people), so in this sentence you have to use the plural "sus caras".
For the life of me, I cannot make the rolling rr sound despite many years of trying. The best I can do is a strange clearing my throat sound which doesn't sound remotely like the Spanish rr. I've been practicing that sound for years and watched every YT vid ever made on how to do it and nothing works. It just ain't happening.
is the web version is messed up or I'm missing something. Cause I entered the exact same thing "Do you remember his face?" and that is shown as incorrect (earlier I'd written "do you remember his face?" and that too was incorrect, I thought duo is being too strict with the capitalization but no, that's not it - what gives?)
