means The thick yellowish fluid that collects at an infection site, made of dead white blood cells, bacteria, and tissue debris.
from Pus comes straight from the Latin pus, meaning exactly the same thing — 'pus' or 'matter.' That Latin word traces back to an ancient Proto-Indo-European root connected to rotting and foulness, a root that's also a distant cousin of the English word 'foul' and the Greek word for pus, 'puon.' So the word has smelled bad, etymologically speaking, for thousands of years.
