Day - Night These words are opposite of each other because our 24 hours are divided into these two time periods. While it is day here it is night on the opposite side of the world. Black - White White is all of the colors reflected in light and black is the complete absence of reflected light. This makes them also the opposite of each other. All and none of the light. Cry - Laugh These two words are opposite because one generally expresses sadness and the other joy. These two emotions are also opposite of each other. As for the word "Morocho," this is not a word I have ever heard here in the U.S. We say blond and brunette are antonyms. One is very light hair, the other very dark hair which makes them opposite because light and dark are opposite.

Me to i never read or haired a this word . But i thin it's batter to say brown as antonym .

hahaha very funny :) . nice to meet you.

I also accept corrections and suggestions about my English in the question :D
