Synonyms & Antonyms

Root Explanation

Nonchalant → It is formed from "non-" (meaning not) and "chalant" (from the Old French *chaloir*, meaning to be warm or to care). The word "nonchalant" describes a state of not being warm or caring, hence conveying a sense of indifference or casualness.

Memory Tip

Think of someone who is 'not' ('non-') 'caring' ('chalant') about a situation — that's why nonchalant means to be indifferent or casual.
