I am studying Spanish. In my textbook it says:
Americans have amazing fashion
Los estadounidenses tienen una moda increíble
Why has "
una" been included? The sentence is clearly talking about fashion, which is not singular, so why use "
This Question/Answer says you have to use
a when referring to persons, but in the example above, it's referring to fashion, which are not people.
Later on the book, it has the following examples:
Tengo dolor de muelas
I’ve got a toothache
No. Tengo un dolor de muelas terrible.
No. I’ve got a raging toothache.
Again, in one "un" is used. In other it is not.
This Question/Answer says you normally use
un to refer to quantity. But then why does one tooth ache have a quantity and the other does not?
When do you include or omit 'a' (un, una)? Based on the examples above, it seems very random.
