Frequently Asked Questions

Is chalant the opposite of nonchalant?

There is no word chalant in English. Nonchalant comes from an Old French word nonchaloir, meaning "to disregard." That word comes from non-, meaning "not," + chaloir, meaning "to concern." If you want a word that means the opposite of nonchalant, both concerned and interested can do the job.

Is nonchalant a bad or negative thing?

Nonchalant can be either negative or positive. The word describes someone who is relaxed and calm in a way that shows that they do not care or are not worried about something. If someone is nonchalant about another person's pain or trouble, the word has a definite negative connotation. But if someone successfully undertaking a difficult task is described as nonchalant, their calmness and relaxed manner can be admirable. If they fail in that task, however, the fact that they were nonchalant will likely be a criticism and explanation for their failure.

What does it mean when someone is nonchalant?

Someone who is nonchalant is relaxed and calm, either because they do not care about something or because they are not worried about something.
