“Fecund” and its synonyms “fruitful” and “fertile” all mean producing or capable of producing offspring or fruit—literally or figuratively. “Fecund” applies to things that yield offspring, fruit, or results in abundance or with rapidity (“a fecund herd”; “a fecund imagination”). “Fruitful” emphasizes abundance, too, and often adds the implication that the results attained are desirable or useful (“fruitful plains”; “a fruitful discussion”). “Fertile” implies the power to reproduce (“a fertile woman”) or the power to assist in reproduction, growth, or development (“fertile soil”; “a fertile climate for artists”).
