"physical movement, muscular action," 1819, from Greek kinēsis "movement, motion," from kinein "to move" (from PIE *kie-neu-, suffixed form of root *keie- "set in motion").
1855, from ice (n.) + age (n.). Perhaps translating German Eiszeit (1837). An earlier term in the same sense was glacial epoch (1841). Local scientific men had noticed from the late 18c. evidence that the Alpine glaciers once had been much larger; in the 1830s stray boulders, moraines, and polished bedrock in northern Europe (formerly interpreted as relics of catastrophic floods) began to be understood as revealing the former presence of a large ice cap there. When Agassiz, a convert to the theory, came to America in 1846 he found similar evidence in New England. The glacial theory and the notion that there had been several worldwide ice ages seems to have been generally accepted by the 1870s.
late 15c. (Caxton), "capable of movement, capable of being moved, not fixed or stationary," from Old French mobile (14c.), from Latin mobilis "movable, easy to move; loose, not firm," figuratively, "pliable, flexible, susceptible, nimble, quick; changeable, inconstant, fickle," contraction of *movibilis, from movere "to move" (from PIE root *meue- "to push away"). Sociology sense of "able to move into different social levels" is by 1927. Mobile home "large trailer permanently parked and used as a residence" is recorded by 1936. Mobile phone is by 1983.
A long-distance number tapped into an Illinois Bell car telephone glowed red on a display. Satisfied that the digits were correct, I pushed the SEND button on the phone. Familiar beeps and boops emerged from the handset. Then, before a half block of this Chicago suburb had slipped by, I was in contact with my New York office.

Croatian separatise movement, 1932, from Croatian Ustaše, plural of Ustaša "insurgent, rebel."
c. 1500, "a sudden movement producing a flash," from glance (v.). Meaning "brief or hurried look" is from 1590s.
social networking Web site, founded in late 2003 and dominant from 2005 to 2009.
"common deck hand, wharf worker," 1868, American English, perhaps from roust + about. But another theory connects it to British dialect rousing "rough, shaggy," a word associated perhaps with rooster. Meanwhile, compare rouseabout "a restless, roaming person" (1746), which seems to have endured in Australian and New Zealand English. With extended senses in U.S., including "circus hand" (1931); "manual laborer on an oil rig" (1948).
