What does enervated mean?
"Enervated" describes someone or something deprived of strength, energy, or vitality — drained to the point of listlessness. A hiker might feel enervated after hours in punishing heat, or a patient after a long illness. The word is formal or literary in tone, appearing more often in polished prose than everyday conversation, where simpler words like "exhausted" or "worn out" would do the same work. It can also describe conditions that sap vigor, as in "an enervating climate." The word is famously deceptive: because it resembles "energy," many readers assume it means energized, when in fact the prefix "e-" here means "out of," and the root is the Latin "nervus," meaning sinew or nerve — literally "to remove the sinews from." Remembering that image makes the true sense hard to forget: to be enervated is to be emptied of one's inner strength.
Lacking vigor, energy, or strength; weakened or drained.
"The long meeting left him so enervated that he skipped lunch entirely."
Formal register; often used of states induced by heat, illness, fatigue, or emotional strain.
Past tense and past participle of "enervate": to drain of vitality or strength.
"The tropical sun enervated the garrison until discipline began to fray."
'Enervated' looks like it should mean full of energy — but thanks to a Latin root meaning 'sinew,' it means exactly the opposite.

Etymology of enervated
"Enervated" comes from the Latin verb "enervare," meaning to weaken or deprive of strength, formed from "e-" (out of) plus "nervus," meaning sinew or nerve — originally suggesting the removal of the sinews that give a body its force. English borrowed the related verb "enervate" around the early seventeenth century, and "enervated" arose as its past participle before settling into use as a straightforward adjective. The same Latin root "nervus" gives us familiar words like "nerve," "nervous," and "innervate."
