galling

The insult starts in a body fluid. In Old English, galla and gealla named gall, the bitter yellow stuff inside the body, and medieval medicine loved turning that sort of physical sharpness into a theory of temperament. If your humors were off, your mood could curdle too, which is why gall slid so easily from “bile” to “rancor” and then to the modern sting of “galling.” By the 1580s, English had turned that old bitterness into a neat participle, as if annoyance itself had been scraped raw and left exposed. It’s the same family that gives us words of irritation like chafe and fret, while gall also keeps its separate life as “nerve” or “bold impudence” — a strange little semantic knot where bitterness and brazenness end up sharing a hallway. So when something is galling, it isn’t just annoying; it feels like the language is tasting bile.
