insouciance
noun
aⁿ-süs-ˈyäⁿs 
Did you know?
Don't worry; be insouciant. Perhaps your mind will rest easier if we explain that English speakers learned insouciance (as well as the adjective insouciant) from the French around the early 1800s. The French word comes from a combination of the negative prefix in- and soucier, meaning "to trouble or disturb." Soucier, in turn, traces to sollicitus, the Latin word for "anxious." If it seems to you that sollicitus looks a lot like some other English words you've seen, you're on to something. That root also gave us solicit (which now means "to entreat" but which was once used to mean "to fill with concern or anxiety"), solicitude (meaning "uneasiness of mind"), and solicitous ("showing or expressing concern").
Synonyms
- apathy
- casualness
- complacence
- disinterestedness

- incuriosity

- indifference
- nonchalance
