invariable adjectives

Question

It appears that some adjectives don't change with number or gender. Perhaps 'macho', 'hembra', 'rosa', and 'naranja' can all be considered denominals. Is there a comprehensive list of invariable adjectives ? Recently, I realized that 'cada' is another exception.

Answer 1

I mentioned that the Spanish adjective "alerta" meaning "alert" is also invariable. It would seem however, that this is borrowed from the Italian phrase "all' erta" which means "on the watch". So "alerta" is not really an adjective, it just looks like one.

Answer 2

Well, cada could not be cado because

Cado [cah'-do] noun = Ferret-hole.

The adjective "alerta" meaning "alert" is also invariable. "Está tenso y alerta." - Alandio, May 24, 2010
