Did you know?

What's the difference between copious, ample, and plentiful?

Copious dates to the 14th century, during the era of English known as Middle English. Like most terms entering the language then, it comes ultimately from Latin, from the word copia, meaning "abundance." (Cornucopia combines this same root with cornu, meaning "horn," to form the phrase "horn of plenty.") Latin copia combines the prefix co- and -op, * ops, meaning "wealth" or "power." (That asterisk means that ops is assumed to have existed or has been reconstructed by means of comparative evidence.) The latter also features in the history of opulent, meaning "wealthy" or "luxurious."
