Transferred sense of "small character or part that stands out from other minor parts" in a play, etc., is from 1928, from earlier meaning "short literary sketch or portrait" (1851), a transferred sense from cameo silhouettes.
camera (n.)youdaoicibaDictYouDict
1708, "vaulted building," from Latin camera "vaulted room" (source of Italian camera, Spanish camara, French chambre), from Greek kamara "vaulted chamber."

The word also was used early 18c. as a short form of Modern Latin camera obscura "dark chamber" (a black box with a lens that could project images of external objects), contrasted with camera lucida (Latin for "light chamber"), which uses prisms to produce on paper beneath the instrument an image, which can be traced. It became the word for "picture-taking device" when modern photography began, c. 1840 (extended to television filming devices 1928). Camera-shy is attested from 1890. Old Church Slavonic komora, Lithuanian kamara, Old Irish camra all are borrowings from Latin.

camouflageyoudaoicibaDictYouDict
1917, noun, verb, and adjective, from French camoufler, Parisian slang, "to disguise," from Italian camuffare "to disguise," which is of uncertain origin, perhaps a contraction of capo muffare "to muffle the head." Probably altered by influence of French camouflet "puff of smoke," on the notion of "blow smoke in someone's face." The British navy in World War I called it dazzle-painting.
Since the war started the POPULAR SCIENCE MONTHLY has published photographs of big British and French field pieces covered with shrubbery, railway trains "painted out" of the landscape, and all kinds of devices to hide the guns, trains, and the roads from the eyes of enemy aircraft.

Until recently there was no one word in any language to explain this war trick. Sometimes a whole paragraph was required to explain this military practice. Hereafter one word, a French word, will save all this needless writing and reading. Camouflage is the new word, and it means "fooling the enemy." ["Popular Science Monthly," August 1917]
camp (n.)youdaoicibaDictYouDict
"place where an army lodges temporarily," 1520s, from French camp, from Italian campo, from Latin campus "open field, level space" (also source of French champ; see campus), especially "open space for military exercise."

A later reborrowing of the Latin word, which had been taken up in early West Germanic as *kampo-z and appeared originally in Old English as camp "contest, battle, fight, war." This was obsolete by mid-15c. Transferred to non-military senses 1550s. Meaning "body of adherents of a doctrine or cause" is 1871. Camp-follower first attested 1810. Camp-meeting is from 1809, originally usually in reference to Methodists. Camp-fever (1758) is any epidemic fever incident to life in a camp, especially typhus or typhoid.
