Why “enervation” is a great word
ENERVATION — [Noun] A profound weakening or draining of vitality, or the state of being thus drained. From Middle French énervation, from Late Latin enervation-, enervatio, from Latin enervatus (past participle of enervare 'to weaken', from e- (variant of ex- 'out') + nervus 'sinew, nerve') + -ion (suffix forming nouns). Unlike languor, which suggests a pleasant, dreamy inertia, or fatigue, which denotes a temporary tiredness from exertion, enervation implies a chronic, systemic sapping of one's core vigor. It is the hollow ache in the limbs after a long fever, the mental fuzz after days of unrelenting stress, and the specific limpness of a spirit drained by petty, endless demands—the quiet catastrophe of having one’s sinews drawn out, leaving only the shape of a self behind.
