What does enervation mean?
Enervation is a formal noun describing a state of profound exhaustion — a draining away of physical energy, mental sharpness, or vitality. It can also refer to the process of weakening something, such as an institution or an argument, by gradually sapping its force. The word derives from the Latin enervare, 'to weaken,' literally built on nervus, meaning sinew or nerve; to enervate someone is thus, etymologically, to remove their very sinews of strength. In modern usage, eneration often appears in literary, medical, and critical writing to convey more than ordinary fatigue — it suggests a deep, lingering depletion, whether brought on by heat, illness, overwork, or moral discouragement. Its connotations are negative and somewhat elevated in tone, making it a precise choice when writers want to distinguish crushing weariness from everyday tiredness.
A state of physical or mental exhaustion and loss of vitality.
"The tropical humidity produced an enervation that made even small tasks feel monumental."
Often used with 'a sense of' or 'physical/mental' as modifiers.
The act or process of weakening someone or something; the sapping of strength, vigor, or effectiveness.
"He warned that constant infighting would lead to the enervation of the party's reform agenda."
Rarely pluralized; the word is almost always used as an uncountable mass noun referring to a state or process.
"The memoir catalogued the various enervations that had marked his long convalescence."
Despite looking like it should mean 'nerving up,' enervation means exactly the opposite: to enervate is to drain the nerve right out of someone.

Etymology of enervation
Enervation comes from the Latin verb enervare, meaning to weaken or deprive of strength, formed from ex- ('out of') and nervus ('sinew, nerve'), so its literal sense is to strip away the sinews. English adopted the noun in the early 17th century, alongside the verb enervate. It shares its root with nerve and nervous, which entered English through Old French from the same Latin source.
