What does achy mean?
Achy is an adjective describing a continuous, dull, low-grade pain — the kind of diffuse soreness felt in muscles and joints after exercise, during illness, or with fatigue, as distinct from sharp or stabbing pain. It is most often used of the body: one feels achy all over with the flu, or has achy shoulders after a long day at a desk. Less commonly it extends figuratively to emotions, as in an achy sense of longing or nostalgia. The word derives from 'ache', a noun and verb of Old English origin (acu, acan), with the adjectival suffix '-y'; related formations include earache and headache. Informal but widely accepted, 'achy' appears frequently in everyday conversation, patient descriptions of symptoms, and casual writing. Its near-synonyms include sore, tender, stiff, and aching, though each carries slightly different nuances: 'sore' suggests tenderness on touch, while 'achy' implies a persistent internal dullness.

That word you reach for every flu season — 'achy' — is simply 'ache' wearing an adjective's coat, a formation English has been making since the Middle Ages.
