autograph [autograph 词源字典]: autograph: [17] Greek auto- was a prefixal use of the adjective autós, meaning ‘same, self’. Many of the commonest auto- words in English, including autograph itself and also autocrat [19], automatic [18] (a derivative of automaton [17], which was formed from a hypothetical base *men- ‘think’ related to mental and mind), autonomy [17], and autopsy [17] (originally meaning ‘eye-witness’, and derived from Greek optós ‘seen’, source of English optic), are original Greek formations.

But the 19th and particularly the 20th century have seen a mass of new coinages, notably in scientific and technical terminology, including such familiar words as autism, autobiography, autoerotic, autofocus, autogiro, autoimmune, automotive, autosuggestion, and of course automobile (originally a French formation of the 1870s). Automobile has itself, of course, given rise to a completely new use for the auto- prefix, with the general connotation of ‘motorized transport’, as in autobus, autocar, autocycle, and the German autobahn.

automatic (n.): "automatic weapon," 1902, from automatic (adj.). Meaning "motorized vehicle with automatic transmission" is from 1949.
golf (n.): mid-15c., Scottish gouf, usually taken as an alteration of Middle Dutch colf, colve "stick, club, bat," from Proto-Germanic *kulth- (cognates: Old Norse kolfr "clapper of a bell," German Kolben "mace, club, butt-end of a gun"). The game is from 14c., the word is first mentioned (along with fut-bol) in a 1457 Scottish statute on forbidden games (a later ordinance decrees, "That in na place of the realme thair be vsit fut-ballis, golf, or vther sic unprofitabill sportis" [Acts James IV, 1491, c.53]).

Oh! who a golfer's bride would be,
Fast mated with a laddie
Who every day goes out to tee
And with him takes the caddie.
