What does gallstone mean?
A gallstone is a small, solid, pebble-like mass that develops in the gallbladder or the bile ducts when components of bile — most often cholesterol, but sometimes bilirubin pigments or calcium salts — become overly concentrated and crystallise. Sizes range from grains of sand to stones several centimetres across, and many people carry them without ever noticing. When a gallstone blocks a bile duct, however, it can trigger sudden, intense pain known as biliary colic, along with nausea or inflammation of the gallbladder. Gallstones are common, particularly in middle-aged adults, women, and people who are overweight, and they are usually detected by ultrasound. Treatment ranges from watchful waiting for symptom-free stones to surgical removal of the gallbladder, one of the most frequently performed operations worldwide. The word is a straightforward medical term, used by clinicians and laypeople alike, and carries no figurative meaning beyond its anatomical sense.

Etymology of gallstone
The word combines 'gall', an Old English term ('galla') denoting bile, long associated with bitterness, with 'stone', from Old English 'stan'. It belongs to a family of compound terms in which natural bodily formations are named as stones, paralleling 'kidney stone' and 'bladder stone'. In medical literature the condition is also described with the Greek-derived terms 'cholelith' and 'cholelithiasis', reflecting an older tradition of naming such concretions with Greek roots.
How gallstone is actually used
A purely medical and everyday term with no figurative use; it refers strictly to the pathological concretion, not to bile (which is called 'gall' in older English). The plural 'gallstones' is common when referring to multiple stones or the condition generally.
Easily confused with gallstone
Kidney stones form in the kidneys from mineral deposits in urine, whereas gallstones form in the gallbladder from bile components.
The gallbladder is the organ itself, while a gallstone is an abnormal mass formed inside it.
