Etymology: Astringency is a plain formation: it comes from "astringent" with the suffix "-cy" added. "Astringent" itself traces back to Latin "astringere", meaning "to bind tight" or "draw together", built from "ad-" ("to") and "stringere" ("to draw tight"). The same Latin root that gives "string" and "strict" lies behind the sense of pulling tissues together. The word's core idea is literal: a substance that draws things together. That is why the sensation in the mouth is so specific. Tannins in tea, unripe fruit, or red wine bind to proteins in saliva and the lining of the mouth, which tightens and dries the tissue. The same pulling action, applied to living tissue, is what makes a substance an astringent in medicine. The suffix "-cy" turns the adjective into a noun for the quality itself, so "astringency" names the property of drawing things together rather than any single substance that does it.
