Middle English do, first person singular of Old English don “make, act, perform, cause; to put, to place,” from West Germanic *don (cf. Old Saxon duan, Old Frisian dua, Dutch doen, Old High German tuon, German tun), from PIE root *dhe- “to put, place, do, make” (see factitious).
Use as an auxiliary began in Middle English. Periphrastic form in negative sentences (“They did not think”) replaced the Old English negative particles (“Hie ne wendon”). Slang meaning “to do the sex act with or to” is from 1913. Expression do or die is attested from 1620s. Cf. does, did, done.
first (and last) note of the diatonic scale, by 1754, from do, used as a substitution for ut (see gamut) for sonority’s sake, first in Italy and Germany. U.S. slang do-re-mi “money” is from 1920s, probably a pun on dough in its slang sense of “cash.”
Fasten up or put up; also, dress up. For example, Let’s do up all the gifts in matching paper, or Please help me do up the collar button, or Jane did up her hair for the dance, or The children were all done up in their best outfits. [c. 1800]
do something up brown or do it up brown. Do something thoroughly or very well, as in They really did it up brown for the dinner party. The allusion here is unclear, but it may be to wrapping a package in brown paper. [Mid-1800s]
