Using "vale"

Question

Can you use "vale", in response to "¿Comó estás?" . I always thought of "vale" as more of an agreement, similar to "ok", "right" or "uh-huh" in English but I have heard people in my school use it to mean "regular" or "más o menos". (These students are not native speakers or anything). Thanks.

Answer 1

Vale is not valid word to response ¿Como estas?

vale is acceptance of something, not necesary the best option ... but acceptable, or valid

Answer 2

Not good usage in my book but who knows what the younger generation are saying?

I would mostly use "vale" to say "that works"

Answer 3

Vale has different meanings outside Spain. In certain South American countries "vale" means something closer to "friend", or "bud"
