creep: [OE] Creep is an ancient verb, which has been traced back to Indo–European *greub-. This was the source also of Dutch kriupen and Swedish krypa ‘creep’, and of Lithuanian grubineti ‘stumble’, and links have been suggested with English cripple. The related Indo-European *greug- produced German kriechen ‘creep’. => cripple[creep etymology, creep origin, 英语词源]
