Origin

Late Old English twinn 'double', from twi- 'two'; related to Old Norse tvinnr. Current verb senses date from late Middle English.

two from Old English:
An Old English word from the same source as twain, twelve, twenty, twilight, and twin (all OE), with an ancient root shared by Latin and Greek duo, source of double (Middle English), duo (late 16th century), duplicate (Late Middle English), and other words. The formula it takes two to…appeared in the 1850s in it takes two to make a quarrel, and in the 1940s in it takes two to make a bargain (see also tango). The saying two's company, three's a crowd was originally two's company, three's none, in the 1730s. Before the British currency was decimalized in 1971 twopence or tuppence was a standard sum. To add or put in your twopenn'orth is to contribute your opinion; twopenn'orth is a contraction of twopennyworth meaning ‘an amount costing two pence’, used also for ‘a small or insignificant amount’.
