fever

fever: [OE] The underlying meaning of fever, ‘high temperature’, suggests that it goes back ultimately to Indo-European *dhegh-, *dhogh- ‘burn’ (which also produced English day, favour, and forment). Descended from it was Latin febris ‘fever’, which English acquired during Anglo-Saxon times as fēfor. The modern form of the word is partly due to the influence of the related Old French fievre.
=> day, favour, foment

fever (n.)

earlier also feaver, 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.
