derive: derive: [14] Like rival, derive comes ultimately from Latin rīvus ‘stream’. This was used as the basis of a verb dērīvāre, formed with the prefix dē- ‘away’, which originally designated literally the ‘drawing off of water from a source’. This sense was subsequently generalized to ‘divert’, and extended figuratively to ‘derive’ (a metaphor reminiscent of spring from). English acquired the word via Old French deriver.
=> rival
derive (v.): late 14c., from Old French deriver "to flow, pour out; derive, originate," from Latin derivare "to lead or draw off (a stream of water) from its source" (in Late Latin also "to derive"), from phrase de rivo (de "from" + rivus "stream;" see rivulet). Etymological sense is 1550s. Related: Derived; deriving.
