white: [OE] White goes back ultimately to Indo- European *kwitnos or *kwidnos, which was formed from the same base as produced Sanskrit sveta- ‘white’ and Russian svet ‘light’. It passed into prehistoric Germanic as *khwītaz, which has since evolved into German weiss, Swedish vit, Danish hvid, and English white (Dutch wit comes from a variant of the same Germanic source). Wheat is etymologically the ‘white’ grain. => wheat, whitsun[white etymology, white origin, 英语词源]
