Did you know?

The adjectives conversant and conversational both descend from the Latin verb conversari, meaning "to associate with." Conversant dates to the Middle Ages; an early meaning of the word was simply "having familiar association." One way to associate with others is to have a conversation with them—in other words, to talk. For a short time in the 19th century conversant could mean "relating to or suggesting conversation," but for the most part that meaning stayed with conversational while conversant went in a different direction. Today, conversant is sometimes used, especially in the United States, with the meaning "able to talk in a foreign language," as in "she is conversant in several languages," but it is more often associated with knowledge or familiarity, as in "conversant with the issues."
