Did you know?

Concomitant was introduced into English at a time when many people were criticizing the use of Latinate forms in favor of more "native" words from Old English. As a descendant of Latin concomitari ("to accompany") and ultimately of "comes," the Latin word for companion, "concomitant" may well have been initially derided as an ostentatious inkhorn term. Indeed, two associated words, the verb concomitate, meaning "to accompany," and another adjective, concomitaneous, meaning "of a concomitant nature," didn't survive to accompany "concomitant" into the 18th century.
