Hey Wat, you change your Name. pretty cool, it easier now! Well Triston. Actually, both "unos" and "algunos" have a pretty similar meaning with some subtle difference they both indicate something near "some" but here is the key Unos: is the masculine plural form of "unos" and it's mean is quite similar to some, but watch out! it doesn't indicate a limited number or little amount of the thing that you are talking about, it only means that not all ex some day... = unos dias... so as you can see, it only indicates that not all days but just some of the days ( without saying a few dais either! ) and right here i have to go nasty, cuz even when Wat is my friend i got to say "unos" is widely used, even more than algunos! sorry pal! On the other hand is "algunos" that also indicates that some of " " whatever your talking about, but at the same time, shows that are the less of " " whatever of what you are talking about. Like Wat says, "a few" is a great translation but altogether with "some" Ex: ... yes, but only sometimes = si, pero solo algunas veces! OK, i hope it helps!

i have a pair of jeans yo tengo unos pantalones (it means, you are talking about one WHOLE thing, with two parts included) i have some sweaters yo tengo algunos sueteres (it means you have more than one sweaters. not many)

Unos/Unas is the plural of Uno/Una. Una silla = a chair Unas sillas = chairs To be honest, I think it is barely used. I've never even seen it written somewhere. Algunos/Algunas means "a few/several" : Algunas sillas = A few/several chairs I don't think "unos/unas" is ever used in a phrase. If you want to say "I have chairs", you can just say "Tengo sillas", and not "Tengo unas sillas" And to say "I have a few/several/some chairs", you can say "Tengo algunas sillas".
