I was wondering if "el ala" belonged to those group of nouns that start with an "a", where the definite article changes from LA to EL.
I also read that the indefinite article "UN" instead of "UNA" can be used before these nouns. I was wondering if this is an optional choice of a strict requirement.
Is "una ala" completely wrong or are both "un ala" and "una ala" correct?
Thank you.
