Cantilevering refers to the engineering technique of supporting a structure or object by means of a cantilever, or a beam or member that is fixed at only one end. Synonyms for cantilevering include overhanging, projecting, and extending. These words are all used to describe the same basic idea of creating a counterbalance to support weight or force in a structure. Other synonyms for cantilevering might include suspending or balancing, as these words also describe the idea of holding or supporting weight at a distance from the base or support structure. Ultimately, the choice of synonym will depend on context, application, and intended meaning.
