Spanish language Q&A Forum

I know that letters in Spanish are feminine, but I notice in this reading that the acronym DNI is proceeded by a masculine article.  Is that because the word "documento" is masculine?  Or are all acronyms masculine in Spanish?

nos sentamos en una banqueta, de lo más felices mientras la música....

In the lesson on emphasis all the examples use a masculine singular adjective ( I put de lo más contento ) but was marked wrong. Is it really wrong?

Gracias

Como ves, mamá sabía que si ellos comían de ese fruto, pensarían que ya no la necesitaban.

Por qué hay una coma entre y otra coma después de ?

But correct answer is "...and can be unstable" (the weather') y puede 

SER variable / cambiante / inestable.  (I put puede estar variable)

I think = creo = I create. How would someone know which I mean?

I have a question about the sentence: "Le dare el dinero que le debo por si acaso se me olivida despues."  If I understand, this sentence expresses the idea that the speaker feels that it is fairly likely that they will forget.  If they thought that it was unlikely that they would forget, then the conditional clause would say "..se me olvidara".  So myy question is: What if the main clause were in el preterito indefinido (Le di el dinero...)?  Would the conditional clause still need to be "...se me olvidara"?  If the speaker considers the condition in the subordinate clause to be less probable, the conditional clause would use the imperfecto do subjunctivo (...se me olividara) whether the main clause refers to a future action or a past action?  Is this correct?Sorry, I don't know how to type accents.
