rely
UK: rɪˈlaɪ | US: rɪˈlaɪ
vi. to depend on with full trust or confidence
vi. to be dependent for support or success
The word "rely" originates from Old French relier (to fasten, attach), derived from Latin religare ("to bind back"). The prefix re- implies repetition or intensity, while -ly (from ligare, "to bind") conveys connection or dependence. Over time, the literal sense of physical binding evolved into the abstract meaning of trusting or depending on someone/something, as if metaphorically "bound" to their support.
