"battles among fellow citizens or within a community," from civil in a sense of "occurring among fellow citizens" attested from late 14c. in batayle ciuile "civil battle," etc. The exact phrase civil war is attested from late 15c. (the Latin phrase was bella civicus). An Old English word for it was ingewinn. Ancient Greek had polemos epidemios.
Early use typically was in reference to ancient Rome. Later, in England, to the struggle between Parliament and Charles I (1641-1651); in U.S., to the War of Secession (1861-1865), an application often decried as wholly inaccurate but in use (among other names) in the North during the war and boosted by the popular "Battles and Leaders of the Civil War" series published 1884-87 in "Century Magazine."
"The war between the States," which a good many Southerners prefer, is both bookish and inexact. "Civil war" is an utter misnomer. It was used and is still used by courteous people, the same people who are careful to say "Federal" and "Confederate." "War of the rebellion," which begs the very question at issue, has become the official designation of the struggle, but has found no acceptance with the vanquished. To this day no Southerner uses it except by way of quotation .... "The war of secession" is still used a good deal in foreign books, but it has no popular hold. "The war," without any further qualification, served the turn of Thucydides and Aristophanes for the Peloponnesian war. It will serve ours, let it be hoped, for some time to come. [Basil L. Gildersleeve, "The Creed of the Old South," 1915]
"one who leads a military patrol in formation in a jungle, etc.," 1944, said to be from point (n.) in military sense of "small leading party of an advance guard" (1580s) + man (n.). A more literal sense also is possible. Point (n.) in U.S. also meant "position at the front of a herd of cattle," and pointman in this sense is attested by 1903.
also maneater, c. 1600, "a cannibal," from man (n.) + eater. By 1829 in reference to the great white shark; by 1840 of tigers in India that have acquired a taste for human flesh and have a special propensity for killing and eating humans; later also of lions. Also used of horses that tend to bite (1840). By 1906 of women (the female equivalent of a womanizer). Related: Man-eating.
The term Man-eater is applied to those Tigers, which, deserting their usual haunts in the jungle, frequent the neighbourhood of Villages, and prey chiefly on men. They are almost invariably found to be old animals, and generally females. They are usually very cunning and cowardly. [Capt. Walter Campbell, "The Old Forest Ranger; or, Wild Sports of India," 1842]
also apeman, hypothetical "missing link" between the highest anthropoid apes and human beings, progenitor of the human race, 1869, in a translation of Haeckel, from ape (n.) + man (n.). Man-ape is attested from 1823 as "anthropoid ape, orangutan." The name Martin Halfape appears in an English roll from 1227.
