The Vietnamese word "đen đét" is an adjective that describes something that is very black or dark. It's often used to emphasize the intensity of the color black.
In more advanced contexts, "đen đét" can also be used metaphorically to describe emotions or atmospheres. For example, you might say: - "Tâm trạng của tôi hôm nay thật đen đét." (My mood today is really gloomy.)
While "đen đét" primarily refers to color, it can also evoke feelings of negativity or sadness when used in certain contexts. For example, one might describe a very dark room or a somber mood as "đen đét."
