N:1. – trench: Late 14c., “track cut through a wood,” later “long, narrow ditch” (late 15c.), from Old French trenche “a slice, cut, gash, slash; defensive ditch” (13c., Modern French tranche), from trenchier “to cut, carve, slice,” possibly from Vulgar Latin trincare, from Latin truncare “to cut or lop off” (see truncate). Trenches for military protection are first so called c.1500. Trench warfare first attested 1918. Trench-coat first recorded 1916, a type of coat worn by British officers in the trenches during World War I.
– fever: Late Old English fefor, fefer “fever, temperature of the body higher than normal,” from Latin febris “fever,” related to fovere “to warm, heat,” probably from PIE root *dhegh- “burn” (cognates: Gothic dags, Old English dæg “day,” originally “the heat;” Greek tephra “ashes”); but some suggest a reduplication of a root represented by Sanskrit bhur– “to be restless.”
The Latin word was adopted into most Germanic languages (German Fieber, Swedish feber, Danish feber), but not in Dutch. English spelling influenced by Old French fievre. Alternative to Old English hrið, hriðing (cognate with Old High German hritto, Irish crith, Welsh cryd, Lithuanian skriečiù). Extended sense of “intense nervous excitement” is from 1580s. Also as a verb in Old English, feferian.
2. An intermittent fever characterized by intervals of chills, fever, and splenomegaly each of which may last as long as 40 hours. It is caused by Bartonella quintana and transmitted by the human louse.
