twist: [OE] Twist appears to come ultimately from prehistoric Germanic base *twi- ‘double’, which also underlies English twice, twig, twin, etc. In Old English it is found only in compound words, denoting such things as ‘rope’ (presumably originally made from ‘two’ strands) and ‘forked objects’. It does not appear as an independent word until the 14th century, by which time its association with ‘rope’ had given it the sense ‘wrench, wind’. => two[twist etymology, twist origin, 英语词源]
