exudar

Exudar is a verb used in Portuguese and Spanish with the basic sense of releasing or leaking a liquid slowly from a substance, surface, or organism. It can also refer to the emission of odors, vapors, or other substances. Beyond the physical sense, exudar is used figuratively to indicate that a quality, impression, or atmosphere emanates from something or someone.

Origin and scope: the term derives from Latin exudare, formed by ex- meaning out and a root related to sweat or seeping fluids. This etymology reflects the idea of liquids or substances gradually moving outward from a material.

Common usages: in everyday language, exudar describes natural leakage, such as resin, moisture, or sap seeping from wood or plants, or vapor emanating from metal or stone. In medical and biological contexts, the noun exudado (Spanish) or exsudato/exudato (Portuguese) denotes a liquid discharged from tissues, often as part of an inflammatory process; the process itself is exudação or exudação. Medical classifications may distinguish seroso, purulento, or sanguinolento exudate. In scientific writing, exudar may describe gases, fluids, or other substances passing through porous materials.

Figurative use: exudar is also employed to convey that a person or place radiates a quality, such as confidence, calm, or authority, e.g., “exuda confiança.” In many varieties, this sense is formal or literary and can be substituted with irradiar, emanar, or transparecer depending on tone.

In summary, exudar covers physical seepage and emission as well as metaphorical emanation of traits, with specialized medical terminology for clinical discharges.
