Ultimate origin

Etymology

The table attendant is inherited from Middle English sewer, an aphetic form borrowed from Anglo-Norman asseour (“one who seats”),[2][3][4][5][6] from Old French asseoir (“to cause to sit, to seat”),[2][3][6] Latin assideō (“to sit beside, attend upon”), from ad- and sedeō (“to sit”).[2][7][4] The fuller form assewer is recorded later than the short one.[2] The Anglo-Norman Dictionary lists asseour among the spellings of assaiour, a tester, including the king's food-taster.[8] Johnson (1755) explained the name from the officers who set the dishes on the table.[9]

Earliest recorded meaning

An attendant at a meal who arranged the table, seated the guests and tasted and served the dishes: before 1387, in Trevisa's translation of Higden's Polychronicon.[2] The Middle English Dictionary records the full form asseour for an officer who saw to the laying of the table and the seating of guests.[10]

Semantic evolution

The word belonged to the great medieval household, where the sewer could be an officer of high rank.[6] It was used figuratively from the 16th century,[2] and there was a verb sewer, to act as sewer at a meal, from about 1553 to 1647.[2] Milton, quoted by Johnson, wrote of a feast "Serv'd up in hall with sewers and seneshals".[9] The word is now used only in historical writing.[5][3]

Ultimate origin

Etymology

The drain is inherited from Middle English seuer, also suer,[10][11][12] borrowed from Anglo-Norman sewere,[11][12][7][3] corresponding to Old Northern French seuwiere (“channel carrying off the overflow from a fishpond”).[2][11][3][13] This goes back to Vulgar Latin *exaquāria, from *exaquō (“to drain off water”), from Latin ex- (“out”) and aqua (“water”),[2][3][14][6] the base also of Old French essever (“to drain off”) and esseveur.[2][6][4] The Latin feminine adjective aquāria (“pertaining to water”) is part of the same formation,[11][7][12] and ewer has a similar history.[11][15] The Anglo-Norman word is recorded from 1376 for a drainage canal,[8] and Weekley notes that until the 16th century the word appears mostly in Anglo-Norman and Medieval Latin legal documents, as Medieval Latin sewera.[15][11]

Earliest recorded meaning

An artificial watercourse for draining marshy land and carrying surface water off to a river or the sea: in a document from New Romney of 1402–3.[2][10][12] It appears in surnames from the late 13th century, such as Robertus Atte Suor.[11]

Semantic evolution

In Middle English the word was a trench or ditch for drainage, and the Commissioners of Sewers, recorded from 1444, were a court that looked after drainage and defences against the sea.[10][2] The modern sense, a covered channel, now usually underground, for carrying away waste water and refuse from houses and towns, is first quoted from Shakespeare's Troilus and Cressida (1609),[2] and became the main sense after about 1600.[11] Figurative use, for a place or channel of filth, dates from the 1640s.[11][2] Weekley notes the old variant shore, as in the London place name Shoreditch.[15] The verb "to provide with sewers" is from 1854; an earlier verb "to drain" is recorded only in 1565.[2][5] The derivatives sewage and sewerage are 19th-century English formations.[14][16]
