The word "dis-cumbered" refers to being relieved of an unnecessary burden or obstacle. An antonym, therefore, would be a word that means burdened, obstructed, or hindered. Some possible antonyms for "dis-cumbered" include encumbered, hindered, hampered, impeded, obstructed, or burdened. These words imply a state where one is held back or restricted in some way. For instance, an encumbered person might be weighed down by heavy bags, or an obstructed individual might be prevented from moving forward. Thus, antonyms for "dis-cumbered" describe a situation that is quite different from the sense of freedom and ease that the original word conveys.
