Frequently Asked Questions

What is the difference between enervate and innervate?

Enervate has the twin misfortune of sharing a beginning with energize and an ending with invigorate, causing many people to assume that it must overlap with these two words in meaning. However, it is roughly the opposite, meaning "to lessen the vitality or strength of." This is a common mistake, but has not yet become so common as to be accepted.

Yes, enervate can function as an adjective, with the meaning of "lacking physical, mental, or moral vigor." An example of such adjectival use can be found in the poem Ode to Drowshood, by Charles G.
