The term 'hitches on' generally denotes the act of attaching or joining two separate entities together. However, the word 'antonym' implies the opposite meaning of a particular word or phrase. So, if we focus on antonyms for the word 'hitches on,' they could include detach, disconnect, separate, or unfasten. These antonyms suggest the act of removing or separating two things that were previously joined or attached. For instance, when you detach a trailer from a truck, you undo the hitch that was connecting them. Thus, understanding the antonyms of 'hitches on' can help us create a context where separation or detachment is more appropriate than attachment or combination.
