adj

Etymology: From Middle French fécond, from Latin fēcundus (“fertile”), which is related to fētus and fēmina (“woman”).

1. Highly fertile; able to produce offspring.

   “The number of children per woman depends, as has been said, on biological and social factors which determine: (1) the frequency of births during a woman's fecund period, and (2) the portion of the fecund period--between puberty and menopause--effectively utilized for reproduction.”

   “The druids […] believed that mistletoe could make barren animals fecund, and that it was an antidote to all poisons.”

2. Leading to new ideas or innovation.

   “This idea of Aristotle's has proved marvellously fecund; and in truth it is the only idea covering quite the whole area of cenoscopy that has shown any marked uberosity.”
