Étymologie

From earlier risque, from Middle French risque, from Old Italian risco (“risk”) (modern Italian rischio) and rischiare (“to run into danger”). Displaced native Old English pleoh (“risk”) and plēon (“to risk”).
speculation on earlier roots
Most dictionaries consider the etymology of these Italian terms uncertain, but some suggest they perhaps come from Vulgar Latin *resecum (“that which cuts, rock, crag”) (> Medieval Latin resicu), from Latin resecō (“cut off, loose, curtail”, verb), in the sense of that which is a danger to boating or shipping; or from Ancient Greek ῥιζικόν (rhizikón, “root, radical, hazard”).
A few dictionaries express more certainty. Collins says the Italian risco comes from Ancient Greek ῥίζα (rhíza, “cliff”) due to the hazards of sailing along rocky coasts. The American Heritage says it probably comes from Byzantine Greek ῥιζικό, ριζικό (rhizikó, rizikó, “sustenance obtained by a soldier through his own initiative, fortune”), from Arabic رِزْق (rizq, “sustenance, that which God allots”), from Classical Syriac ܪܘܙܝܩܐ ,ܪܙܩܐ (rezqā, rōzīqā, “daily ration”), from Middle Persian [script needed] (rōčig), from Middle Persian [script needed] (rōč, “day”), from Old Persian [script needed] (*raučah-), from Proto-Indo-European *lewk-.
