Detumescence

Part of speech: noun

Definitions

1. The process of subsiding from an erect or swollen state to a normal or less engorged condition; the reduction of swelling or tumescence often in biological tissues; a state change where increased blood flow or engorgement diminishes
2. A biological occurrence whereby an organ or tissue transitions from a swollen or erect form back to its usual size or flaccid state; the decrease of engorgement following stimulation; the physiological reversal of tumescence
3. The return from a swollen or heightened state to baseline volume or firmness in bodily parts; the natural subsidence after expansion or erection; a phase marking diminished turgidity or swelling in tissues

Etymology: "Detumescence" is a plain formation: the prefix "de-", meaning "down" or "away from," attached to "tumescence," the state of swelling. The prefix traces back through Latin "dē," meaning "down from" or "away," to ancient roots meaning something like "from" or "away," and it entered English as a living part of the language, used to reverse or undo a process. Attaching it to "tumescence" produces a term for the subsidence of swelling. Tumescence itself comes from the Latin "tumescere," "to begin to swell," built on "tumere," "to swell." "De-" added to such a stem gives a precise opposite: where tumescence describes the swelling up, detumescence describes the going back down.
