This question already has an answer here:

I take a beginners spanish course in school and came across this blip one day. I was trying to describe a girl in a photo wearing pink socks as la niña lleva calcetines rosas. My teacher then said that I would have to change the rosas to rosa because it didn´t sound natural, then came to the realization that all color adjectives naturally ending in -a stay singular regardless of the noun they are attached to.

We didn't get the time to corroborate the theory with non-color adjective as it was the end of class, but does it apply to all feminine, i.e. -a ending adjectives? Or is the theory correct for all such color adjectives in the first place?

Edit: I believe the question I had unknowingly duplicated had the same essence as mine did, but the answers on the use of the noun/adjective café did not answer my question from the perspective of feminine adjectives, at least from what I understood of it.

  • I don't think so. You can either say la niña lleva calcetines rosados, perfectly idiomatic. – Alejandro Feb 3 '16 at 5:54

    Where's your teacher from? I'd actually feel weird if I said "calcetines rosa". "Calcetines rosas" is far more commonly heard (at least in Spain), to the extent that "calcetines rosa" sounds wrong over here. "Calcetines de color rosa" is okay. – Yay Feb 3 '16 at 6:20
  • It would be just "rosa" if it is with the word "color". This way: "la niña lleva calcetines (de) color rosa". "De" preposition can or cannot be placed there. When it is an adjective, it should match plural. By the way, in this part of the world (I live in Chile), more natural is the word "rosado".... that is, "la niña lleva calcetines rosados" – jstuardo Feb 3 '16 at 11:49

    Voting to reopen. The proposed duplicate doesn't answer "does it apply to all feminine, i.e. -a ending adjectives?" – aparente001 Apr 10 '18 at 11:28

It depends a bit on the dialect and is rooted in the type of word that rosa or marrón or carmesí really is.

If a speaker naturally says dos cosas rosa, thev they are actually using a juxtaposed noun. Nouns need not agree with other nouns, especially given that there tends to be an implied phrase that's highly context sensitive and that normally leaves the other noun singular (for example, with colors, dos cosas (de color) rosa).

For many speakers, the terms are/can become lexicalized as adjectives, at which point they also begin to agree in number and gender where morphologically possible and you would get dos cosas rosas.

For an example of this outside of colors, you can look to the term clave. Originally you would see palabras clave, but over time, palabras claves has become more common.

tl;dr it's fine in both singular (juxtaposed noun) and plural (lexicalized as adjective) forms, but dialectal usage may prefer one over another.

Editor's note: "Does it apply to all feminine, i.e. -a ending adjectives?" No. The set of adjectives that are sometimes used without agreement (such as "rosa" and "clave") is small. The standard rule about agreement of number and gender almost always applies, without regard for dialect or region or personal preference.

  • @aparente I don't see the point of adding a section on editor's note. The post should not have any "meta" information. So it is probably best to leave a comment to the answer and see if the answerer wants to append the info; later on, you can add those parts. – fedorqui Apr 10 '18 at 12:41
  • @fedorqui - Well, I would bring this up in Meta, except that apparently you feel that Meta is overloaded right now. Look, the SE model is precisely the opposite of what you are suggesting. But ultimately I suppose it's up to guifa. There's always the option of rolling back. – aparente001 Apr 10 '18 at 12:49
  • @aparente001 please check When should I edit posts?. Posts are community owned, but it is good practice to comment on them before doing significant changes. – fedorqui Apr 10 '18 at 12:54
  • @fedorqui - "Significant"? Do you really find this edit significant? // I see nothing in the page you linked to that would make my edit unreasonable on principle. But look. If you feel strongly about this, you can roll the answer back. You are welcome to do so, and in that case I'll just put the removed material into a supplemental answer. This is a solvable problem. – aparente001 Apr 10 '18 at 12:57
