rás f[1]

Etymology

It is inherited from Proto-Germanic *rēsō (“a running, course”),[1][2] a feminine ⟨ō⟩-stem.[3] Its cognates are Old English rǣs (“running, attack”) and Middle Low German rās (“strong current”).[2][4] Outside Germanic, Orel and de Vries compare Ancient Greek ἐρωή (erōḗ, “rush, impetus”),[2][5] and Ásgeir Blöndal Magnússon sets it under a root *rē̆s-, *eres- “to flow, run”, with Latin rōs (“dew”).[4]

Cleasby and Vigfússon thought of a connection with renna,[6] but the modern dictionaries relate it instead to the verbs rasa and ræsa and the neuter ras “haste”.[5][7]

Earliest recorded meaning

ONP's first dated record is from 1175, in the Old Icelandic Elucidarius (ONP's Eluc674), of the courses of the heavenly bodies: Sol oc tungl oc stiornor keɴna goþ þuiat þau varþveita staþe rasar siɴnar “Sun and moon and stars make God known, because they keep the station of their course”.[8]

Semantic evolution

ONP puts the senses in the order “running, speed”, “current, stream”, “course of life, of time”, “orbit”, “direction, way”, then the rarer “column of figures”, “channel, opening”, “line, furrow” and “host”.[8] In the sagas the commonest uses are the phrases taka á rás and hefja á rás “to take to one's heels”, and með mikilli rás “at great speed”.[8][9] The Norwegian laws use it of pursuit, the chase after a fleeing man.[10][11]

Icelandic and Faroese keep rás.[4] English race “a running” is either from the Norse word or the Old English rǣs reshaped under its influence,[12] and de Vries also derives a Guernsey French ras “current” from it.[5]
