walk (v.): O.E. wealcan "to toss, roll," and wealcian "to roll up, curl, muffle up," from P.Gmc. *welk- (cf. O.N. valka "to drag about," Dan. valke "to full," M.Du. walken "to knead, press, full," O.H.G. walchan "to knead," Ger. walken "to full"), perhaps ult. from PIE base *wel- "to turn, bend, twist, roll" (see vulva). Meaning shifted in early M.E., perhaps from colloquial use of the O.E. word. "Rarely is there so specific a word as NE walk, clearly distinguished from both go and run" [Buck]. Meaning "to go away" is recorded from c.1460. Trans. meaning "to exercise a dog (or horse)" is from 1470. Walk-up in ref. to an apartment not accessible by elevator is attested from 1919 as an adj., 1925 as a noun. The surname Walker probably preserves the cloth-fulling sense.

massage (n.): 1876, from Fr. massage "friction of kneading," from masser "to massage," possibly from Arabic massa "to touch, feel, handle;" if so, probably picked up in Egypt during the Napoleonic campaign there.

Meaning "money" is from 1851. Doughface was the contemptuous nickname in U.S. politics for Northern Democrats who worked in the interest of the South before the Civil War; it was taken to mean "man who allows himself to be moulded." The source is an 1820 speech by John Randolph of Roanoke, in the wake of the Missouri Compromise.
"Randolph, mocking the northerners intimidated by the South, referred to a children's game in which the players daubed their faces with dough and then looked in a mirror and scared themselves." [Daniel Walker Howe, "What Hath God Wrought," 2007]
make (v.): O.E. macian, from W.Gmc. *makojanan (cf. O.S. makon, O.Fris. makia "to build, make," M.Du. maken, O.H.G. mahhon, Ger. machen), from PIE *mag- "to knead, mix, make" (see may). Sense evolution probably is via prehistoric houses built of mud. Gradually replaced the main O.E. word, gewyrcan (see work). Meaning "to arrive at" (a place), first attested 1620s, originally was nautical. Formerly used in many places where specific verbs now are used, e.g. to make Latin (c.1500) "to write Latin compositions." This broader usage survives in some phrases, e.g. to make water "to urinate," to make a book "arrange a series of bets" (1828), make hay "to turn over mown grass to expose it to sun." Make do "manage with what is available" is attested from 1899. Make time "go fast" is 1887; make tracks in this sense is from 1834. Make the grade is 1912, perhaps from the notion of railway engines going up an incline. Phrase on the make "intent on profit or advancement" is from 1869. To make a federal case out of (something) popularized in 1959 movie "Anatomy of a Murder;" to make an offer (one) can't refuse is from Mario Puzo's 1969 novel "The Godfather." To make (one's) day is from 1909; menacing make my day is from 1971, popularized by Clint Eastwood in film "Sudden Impact" (1983). Related: Making.
