n. the process of producing and releasing a substance from a cell or gland

The word "secretion" originates from the Latin secretio, derived from secernere ("to separate, set apart"), combining se- (apart) and cernere (to sift, discern). The root "secret" reflects the idea of hiding or separating substances internally, while "-ion" nominalizes the process. Over time, it evolved to specifically describe the biological process of glands or cells releasing substances (e.g., hormones, enzymes).

The plant’s nectar secretion attracts pollinators.
