IPA: /dɪˈtjuːmɛsəns/
KK: /dɪˈtjuːmɛsəns/
The process of a swollen area returning to its normal size after being enlarged, often used in medical contexts.
After the injury, the doctor monitored the detumescence of the patient's ankle.
Detumescence → It is formed from "de-" (meaning down or away) and "tumescere" (meaning to swell). The word describes the process of swelling going down or subsiding.
Think of something that is 'going down' ('de-') after it has 'swelled' ('tumescere') — that's what detumescence means.
