“Manducate” might look something like the buzzword “mansplain,” but the former term has nothing to do with explaining or educating. Instead, “manducate” is a fancy term for something everyone does: chewing or eating. In the 16th century, the original English word was “manducation,” which came from the Latin verb “mandere,” meaning “to chew.” The word turned into “manducate” by the 17th century, but it still seems like a very formal term for an activity such as chewing. However, the related Latin word “manduco” meant “guzzler,” so there’s no need to stand on formality.
