How do I say I'm wearing black pants?

"Llevo pantalones negro." or do I have to add an "s" to negro?

Thank you

Absolutely! Here is the basic rule for adjectives in Spanish. Find the NOUN and then all adjectives will have the same number (either singular or plural) and gender (either masculine or feminine) as that noun.

los pantalones = is plural and masculine
negros = now it matches because it is also plural and masculine.

Thank you-I understand it now more clearly

To say "I'm wearing black pants" in Spanish, you would say "Llevo pantalones negros."

In Spanish, adjectives typically need to agree with the noun they modify in both gender (masculine or feminine) and number (singular or plural). Since "pantalones" is a plural noun, the adjective "negro" should also be in its plural form, which is "negros."

Therefore, the correct phrase is "Llevo pantalones negros," with the adjective "negros" agreeing in both gender and number with the noun "pantalones."
