Fecund is an adjective that means highly fertile.
Our word of the day comes from the Latin word for fertile, fecudus (fee KOON doos). Fecund may be used in a medical sense to refer to a pregnant woman, in a botanical sense, to refer to a fecund garden, or, in a figurative sense, as in: Kelly’s fecund mind ever ceases to astonish me. We never know what kind of creative idea she’ll come up with next.
