The word insouciant means “free of worry or anxiety; nonchalant”
This word came into English in the early 1800s
Background / Comments
I keep thinking that this word is a synonym for “insolent” (probably just because the words start similarly). The base of this word is the French word souciant, which is the present participle of soucier (to worry). It is combined with the prefix in- (not). The French word came from the Latin word sollicītāre (to disturb). If I hadn’t been distracted by the similar word “insolent”, I should have been able to figure it out… I know about the Prussian ruler Frederick the Great – he built a castle as a retreat; a place to be free from worry or case, and he called it that: Sanssouci (sans souci – without care”) Palace. Knowing this, I should have been able to parse our word.
