Did you know?
You're more likely to be diligent about something if you love doing it. The etymology of diligent reflects the fact that affection can lead to energetic effort. The word, which entered English in the 14th century by way of Anglo-French, descends from the Latin verb diligere, meaning "to value or esteem highly" or "to love." The Latin diligere was formed by adding the di- prefix (from dis-, "apart") to the verb legere, an ancestor of the English legend, meaning "to gather, select" or "to read." Of course, you don't need to care for the task at hand in order to be diligent, but it certainly does help!
