是先有橙子，还是先有橙色？

Whichcamefirst,theorangeor...orange

Sowhichcamefirst,thecolororthefruitTheansweris...neither.Well,onedidcomebeforetheother,butneitherwasactuallythefirstmeaningoftheword.Theword“orange”wasactuallyfirstusedtodescribethetreethatthefruitgrowson.

Astimewenton,thewordcametomeanthefruit,notjusttheorangetree.Backtothe13thcenturyAD(公元),thewords“pumeorange”whichcamefromOldFrenchmeant“thefruitfromtheorangetree”.

“Orange”didn’tcometodescribeacoloruntilalmost200yearslater,makingthefruittheclearwinner.In1512,forthefirsttime,theword“orange”wasusedtodescribethecolor.AccordingtotheOxfordEnglishDictionary,theuseofthewordfirstappearedinawill(遗嘱).

So,theonlymysterythatremainsis—howdidpeopledescribethecolorbefore1512AccordingtoHuffingtonPost,speakersofOldEnglishusedtheword“geolurēad”,meaning“yellow-red”.ThankstoOldFrench,thecolororangehasanameofitsown.
