If you've done something so much that it doesn't excite you anymore but just leaves you tired, consider yourself jaded. If someone says you look a little jaded, it just means that you look tired.

Pronunciation: /'dʒedɪd/
English Description: depleted of strength or energy
Synonyms: exhausted
Chinese Translation: 厌倦的(yan4 juan4 de)
Spanish Translation: harto
STORY: The history of jaded is not clear, but perhaps it is related to the noun jade, an old term for a worn-out horse. Even if not, picturing a tired old horse may be a nice way to remember that jaded means dulled or tired from too much of something. The word can also mean cynical because of bad experiences with something, like a jaded journalist who doesn't see the person behind the politician.

EXAMPLE SENTENCE:

Perhaps we're jaded, but most clips are of the "been there, done that" variety.
One reason repression survives, as reporters haranguing jaded editors have long known, is that it is repetitive.
