numbers have gender?
how do you differentiate between 'one suitcase' and 'a suitcase'?
uno maleta una maleta

You use "una" maleta for both. If you think about it "a" suitcase means "one" suitcase.
For masculine use "un" as in "un chico" which can be "a" boy or "one" boy.

Here is an edit.
A car is parked in the street. "Un coche está estacionado en la calle." This could also mean "one" car is parked, etc.
A girl is getting into the car. "Una muchacha sube al coche." This could also mean "one" girl is getting--etc.
There are cases such as Falda Escocesa pointed out where the indefinite article is not used. but I believe you wanted to see how the gender is applied when you do use it. Please leave a comment below so that I may be sure that I have addressed your question properly.
This can be difficult.
Only the other day, on a visit to see my husband in hospital, I happened to get into the lift with a kind-looking Spanish woman who asked which floor I wanted. I asked her:¿ should it be El uno o la una?
She laughed and said she had never considered the matter but, yes, La una, referring to LA planta... Then she said I spoke good Spanish and I nearly fainted from happiness , right there in the hospital lift.
While I bow to Dani's obvious mastery of Spanish, it seems to me that Spanish sometimes drops the indefinite article where English would not, yet might take it up again in order to reflect the fact that the speaker means to emphasise they have one (as opposed to two or three) of something. For example:
- Tengo coche = I have a car (no article in Spanish)...
- Tengo un coche y dos motos = I have one car and two motorbikes...
I think I've got this right, but maybe Dani would be kind enough to clarify ![]()
