Effete is an adjective describing something as feminine or effeminate. An alternative definition is for something to lack effectiveness, to not have strength or bravery or to be unable to act.
Its derivatives include effetely and effeteness.
In the seventeenth century, effete meant being past the childbearing years, or to not be fertile. One can see the transition of this to other topics, so that governments and armies were not fertile, or ineffective.
