Etymology

It is from Ancient Greek φλέγω (phlégō, “to burn, inflame”) + -μα (-ma).[1][2][3] How the sense passed from “flame, inflammation” to “slime, phlegm” is unexplained.[2]

φλέγω (phlégō) continues Proto-Indo-European *bʰleg- (“to burn, shine”).[2][4] Its nearest relatives are Latin fulgō (“to flash, shine”), flagrō (“to blaze”) and flamma (“flame”), and the Tocharian verb pälk- “to shine, burn”.[2][5][4]

Earliest recorded meaning

Homer has it once, for a flame or blaze, in the Iliad.[6][3]

Semantic evolution

In medicine it first meant inflammation and heat, in the Hippocratic writers and Galen.[3] It then became phlegm, one of the four humours of the body: Herodotus mentions it, the Hippocratic Nature of Man counts it among the humours, Plato's Timaeus makes acid and salty phlegm the source of all catarrhal diseases, and Aristotle contrasts hot bile with cold phlegm.[3][7] Prodicus of Ceos explained the name as what is burnt and overcooked in the humours.[8] “White phlegm” was a kind of dropsy.[3] In poetry it could mean an angry humour, as “the savage phlegm of Archilochus”.[3][9]

Latin borrowed the medical word, and through it French and English: English phlegm is recorded from the late 14th century.[9][10] Modern Greek φλέγμα (flégma) is mucus and, after English phlegm, coolness and composure.[11]
