Questions & Answers about Prefiero la roja.

What exactly does "la roja" mean here?

It’s a nominalized adjective: la roja = “the red one” (feminine), with the noun understood from context (e.g., camiseta, caja, falda).

How do I know whether to use "la roja" or "el rojo"?

Match the gender/number of the understood noun:

• Feminine: la roja (e.g., camiseta).
• Masculine: el rojo (e.g., coche).
• Plural: las rojas / los rojos.

Why is it "roja" and not "rojo"?

Adjectives agree with the (understood) noun in gender/number. If the noun is feminine, the adjective takes -a: roja. La rojo is ungrammatical.

Do I have to include the article? Can I say "Prefiero roja"?
