Forms

Etymology

It is borrowed from Ancient Greek φλέγμα (phlégma, “flame, heat; inflammation; phlegm”),[1][2][3] from φλέγω (phlégō, “to burn”).[4] Köbler traces it to Proto-Indo-European *bʰleg- (“to shine, burn”).[3] It is also spelled flegma.[2]

Earliest recorded meaning

Palladius, in his work on agriculture, uses it of dissolving phlegm.[2][5] Köbler dates him to the end of the 4th or beginning of the 5th century AD.[3]

Semantic evolution

It was a clammy humour of the body, phlegm, a post-classical medical word found in Palladius, Vegetius' veterinary work, Gargilius Martialis and Jerome.[2][6] Isidore explains the name from a Greek word for cold, as phlegm is a cold humour, one of the four humours.[7]

In medieval Latin it was phlegm, mucus, slime.[8][9] Its descendants include Italian flemma, French flegme and Spanish flema.[1] English phlegm is recorded in the late 14th century as one of the four humours, through Old French fleume.[4]
