Did You Know?
Copious derives from Latin copia ("abundance"), which in turn combines the prefix co- and ops ("wealth" or "power"). "Copious" and "opulent" (also from "ops"), along with "ample," "plentiful," and "abundant," all mean "more than sufficient." "Ample" implies a generous sufficiency to satisfy a particular requirement ("ample proof"). "Copious" puts emphasis upon largeness of supply more than on fullness or richness ("copious toasts to the bride and groom"). "Plentiful" implies a rich, and usually more than sufficient, supply ("a plentiful supply of textbooks"). "Abundant" suggests a greater or richer supply than "plentiful" does ("moved by the abundant offers to help"). But use "opulent" when the supply is both abundant and infused with a richness that allows an extra measure of gratification ("the opulent blossoms of the cherry trees").
