Emily derives from the Latin Aemilia, a root often linked to rivalry or striving, though over centuries of use the name has drifted toward suggesting industriousness more than competition. It's commonly read as describing someone diligent and quietly determined, with effort as the throughline rather than conflict.
Consider what things the Planets perform not by their Aspects, and observe if they do them not by their Antisions, for the Antisions have power, and are not to be enumerated amongst Aspects. - William Lilly (1602.-1681.)
