Delete cover denotes the action of removing or erasing something that is covering. Its antonyms, on the other hand, refer to preserving, adding, or keeping something intact. For instance, the antonym of delete could be add, insert, or append, which means to keep, include or add to the existing record or file. At the same time, the antonym of cover can be reveal, expose or unveil, which indicate the act of showing or uncovering something. Therefore, while delete cover means to remove or dispose of something, its opposite terms mean retaining, revealing or preserving something instead.
