twelve

twelve: [OE] Etymologically, twelve probably means ‘two over’ (just as eleven means ‘one over’). It appears to go back to a prehistoric Germanic compound formed from *twa- ‘two’ and *lif- (a relative of English leave), which also produced German zw?lf, Dutch twaalf, Swedish tolf, and Danish tolv. If so, its underlying meaning is ‘two left (over ten)’, hence ‘ten plus two’.
=> leave, two

twelve (adj.)

Old English twelf "twelve," literally "two left" (over ten), from Proto-Germanic *twa-lif-, a compound of the root of two + *lif-, root of the verb leave (see eleven). Compare Old Saxon twelif, Old Norse tolf, Old Frisian twelef, Middle Dutch twalef, Dutch twaalf, Old High German zwelif, German zw?lf, Gothic twalif. Outside Germanic, an analogous formation is Lithuanian dvylika, with second element -lika "left over."
