The antonyms for the word "un-bury" are "bury," "inter," and "entomb." The term "un-bury" means to dig up or uncover something buried. The act of un-burying something could be done intentionally, as in the case of archaeologists digging up ancient artifacts, or by accident, such as finding buried treasure. Therefore, the opposite action of un-burying something would be to cover or bury it again. This is why the words "bury," "inter," and "entomb" are the antonyms for "un-bury." They all mean "to put or place something under the ground," but in this case, it refers to covering an item, rather than uncovering it.
