The Vietnamese word "dơ" is primarily used as an adjective meaning "dirty" or "unclean." It describes something that is not clean, whether it be a physical object, a person, or a place.
"Bàn ăn này dơ, cần phải lau."
(This dining table is dirty; it needs to be cleaned.)
"Chó của tôi rất dơ sau khi chơi ở ngoài."
(My dog is very dirty after playing outside.)
In more complex sentences, "dơ" can also be used metaphorically to describe situations, behaviors, or attitudes that are considered morally or socially unacceptable.
Besides being an adjective for "dirty," "dơ" can also function as a verb meaning "to raise," often referring to raising a hand or an object.
