History and etymology of diligent

The adjective 'diligent' has its etymological roots in Latin. It is derived from the Latin word 'diligentia,' which means 'care' or 'diligence.' This term is formed from 'diligere,' a combination of 'dis' (thoroughly) and 'legere' (to choose or select). In Latin, 'diligere' originally conveyed the idea of choosing or selecting something with care, and it evolved to signify the concept of careful and persistent attention to a task or responsibility. Over time, 'diligentia' became associated with being hardworking, persistent, and dedicated to one's work or responsibilities. When 'diligentia' entered English as 'diligent,' it retained this sense of meticulous care and persistent effort, effectively conveying the qualities of hard work, dedication, and thoroughness.
