Astringent
Etymology
From Latin "astringere" (to bind fast), from "ad-" (to) plus "stringere" (to draw tight) — the same root behind "stringent" and "strict." It literally describes how the compounds draw together and contract the soft tissues of the mouth.
adjective · /uh-STRIN-junt/
Producing a dry, puckering, tissue-tightening sensation in the mouth.
What it names
The specific feeling — not a taste — that strong tea, unripe fruit, and tannic red wine leave, which people often mistake for bitterness.
Example
The young wine was so astringent it seemed to shrink the inside of his cheeks.
Related idea
Distinct from acidity: acidity is a sour taste that makes the mouth water, while astringency is a tactile drying sensation that does the opposite.
adjective · /uh-STRIN-junt/
Sharp, severe, or caustic in manner or expression.
What it names
a bitingly critical quality
Example
Her astringent wit spared no one at the table.
Related idea
The figurative sense borrows the physical pucker — words that make you wince. Compare acidity and tendentious.
