A Spanish guitarist I follow on YouTube posted:
I know what it means, because she provided an English translation, “and compositions I’m creating to show you in a near future”. I’m curious though about os. With Google’s help, I’ve guessed it’s the reflexive pronoun version of vosotros. Is that right? She also uses ustedes though, so that’s confusing. Is that normal usage, or maybe just a pedo cerebral? (That translation is also courtesy of Google.)
According to the Wikipedia table of Spanish Pronouns, os is the accusative 2nd person plural, whereas ustedes is the nominative 2nd person plural. The Nominative case is for when it is used as the subject of the sentence, and the accusative case is used for when it is the object.
I’m pretty sure there is a poster around here from Spain who will be able to answer more authoritatively.
from the context here os is the dative from of vosotros (to you) I am not sure about mixing the ustedes and vosotros forms. That seems odd. I am also not sure why poder isn’t conjugared. But i am not a native speaker.
As a native Spanish speaker from Spain (Latin America may vary) I would say the sentence is not completely correct, as it lacks an “un” (“el” would do as well): "… y composiciones que estoy creando para ustedes y en un futuro cercano poder enseñároslas … " and “os” and “ustedes” are indeed on different levels of politeness (**Zimaane **explained the dative correctly). So I would either say:
… y composiciones que estoy creando para vosotros y en un futuro cercano poder enseñároslas …
or
… y composiciones que estoy creando para ustedes y en un futuro cercano poder enseñárselas …
Finally, as the first part of the sentence explains what he is doing the composing for I would not link both half-sentences with a simple copulative “y” but with a “para” (for) to express finality.
But that is on the level of what Google translated a bit too literally with pedo cerebral, something we in Spain would rather call paja mental or comerse el coco. At least in my age group, I don’t know what kiddies say today.
os = object pronoun referring to more than one person (Like the English you plural)
