The story of the word

Alexander Schmidt named it in the 1870s while working out the chemistry of coagulation; the -in is ordinary chemists' suffix, not Greek. Thrombos in Hippocratic writing was any curdled lump, clotted milk included, before it narrowed to blood. Thrombosis, thrombocyte and the coronary thrombosis on a death certificate all descend from the same lump.
