“Hydropic” historically describes a person swollen with dropsy, a condition in which fluid accumulates in tissues or body cavities. Before modern diagnosis, dropsy was a visible and troubling sign of serious disorders involving the heart, kidneys, liver, or circulation. In poetry, the word can create images of unnatural enlargement, heaviness, and a body losing its proper boundaries. It may also be used figuratively for excess, greed, or emotional surfeit, since swelling becomes a symbol of something dangerously overfull.

"Hydropic" is a formal medical term for being affected by dropsy or severe fluid accumulation (edema). In poetic usage, it carries strong figurative connotations of excessive, unnatural fullness, unquenchable thirst, or morbid swelling. Poets may use hydropic imagery to describe bloated wealth, over-indulgent desires, or stagnant landscapes heavy with damp rot. Explaining this term to students helps expand their vocabulary for analyzing imagery of excess and stagnation, allowing them to trace how 17th- and 18th-century writers turned biological conditions into moral commentary. Related terms include dropsied, edematous, turgid, and bloated.
