Etymology Origin:
The word insouciant entered English in the early 19th century from French, where insouciant literally means "not caring." It combines the negative prefix in- with souci (care), reflecting a lighthearted, untroubled attitude. The Latin root sollicitus (anxious) subtly contrasts with its modern carefree connotation, showcasing how language can invert meanings over time.
