rheumy

The word "rheumy" traces its origins to the ancient Greek concept of bodily fluids. The Greek noun rheuma signified a flow or flux, which in ancient medical theory was applied to the mucous secretions from the eyes or nose. This term passed into Latin as rheuma and eventually into Middle English. The adjectival suffix "-y," of Germanic origin, was appended to form "rheumy," literally meaning "characterized by rheum." Thus, the modern sense describing watery eyes retains the core logic of its ancient root, connecting the literal notion of a flowing substance to a specific physiological condition.

Structure: rheum (watery discharge) + y (adjective suffix) rheum (from Latin rheuma, meaning "a flowing, a stream," itself from Greek rheuma, "a flow, stream, current"); y (from Old English -ig, an adjective-forming suffix meaning "characterized by, full of").
