Provide an example of a pair of antonyms that are also contronyms.

One example of a pair of antonyms that are also contronyms is the word "sanction." In one sense, "sanction" means to approve or authorize something, while in another sense, it means to impose a penalty or punishment. Therefore, "sanction" can be both an antonym (approval vs. penalty) and a contronym (approval vs. punishment).
