Detente is a noun that refers to an easing of tensions between rivals.
Our word of the the day comes directly from French where it refers to ‘a relaxation.’ When imported into English, the word came to refer to a relaxation of tension between nations or regions. In more recent years, it’s just as likely to have the same meaning, but applied to individuals.
I sense there’s detente between Carly and Evan. The two of them seem to be getting along a lot better than they had in the past.
