"Más" and "mas"
I understand that one of the many pairs of homophones in Spanish that are differentiated only by a written accent is "más" (more) and "mas."
What is the usage of "mas"? What does it mean? I've been unable to find a satisfactory explanation of how to use the word and for what.
the word "mas" can be used as but, as rspreng says. In order to differentiate them (more and but) the accent is given to "more". I have checked it out to give you a source, http://lema.rae.es/dpd/srv/search?id=Cbumyr3WLD6Afn24Wr, and it says that actually the pronunciation is different (hence the accent) I never thought about it, as I learned all this when learning about words that sound alike but mean different, but yes, makes sense.
