congestion

Etymology

It is inherited from Middle English congestioun,^[2] borrowed from Old French congestion,^[3][2][4] and directly from Latin congestiō (“a heaping up”),^[3][5][6] a noun of action from congestus, the past participle of congerō (“to bring together, pile up”),^[3][5][7] formed from con- (“together”) and gerō (“to carry”).^[3][8][7] The verb congest was formed from the same participle in the 16th century.^[7] The OED takes the word from French, where it is recorded in the 16th century in Paré,^[9] while Etymonline dates the Old French word to the 14th century.^[3]

Earliest recorded meaning

An accumulation of morbid matter in the body: before 1425, in a Middle English translation of Chauliac's surgery.^[2][3]

Semantic evolution

The word began as a medical term, and the medical sense, an excessive accumulation of blood or other fluid in a part of the body, has lasted to the present;^[4][3][7] Johnson (1755) defined it as "a collection of matter, as in abscesses and tumours".^[10][9] From 1593, in Nashe, it also had the general sense of gathering or heaping together, and since 1664 a heap or pile, both now obsolete.^[9][11][4] In the 19th century it was transferred to overcrowding: the OED records an overcrowded or overloaded condition, as of population or traffic, from 1868,^[9] and Etymonline dates the sense "a crowding together of people, traffic, etc." from 1883.^[3] In 1906 it was also applied to districts that could not support their population.^[9] In medicine the word is now used of blood in the blood vessels or of mucus in the airways.^[4][12]
