camera [camera 词源字典]: camera: [18] Latin camera originally meant ‘vaulted room’ (a sense preserved in the Radcliffe Camera, an 18th-century building housing part of Oxford University library, which has a vaulted roof). It came from Greek kamárā ‘vault, arch’, which is ultimately related to English chimney. In due course the meaning ‘vaulted room’ became weakened to simply ‘room’, which reached English, via Old French chambre, as chamber, and is preserved in the legal Latin phrase in camera ‘privately, in judge’s chambers’.

In the 17th century, an optical instrument was invented consisting of a small closed box with a lens fixed in one side which produced an image of external objects on the inside of the box. The same effect could be got in a small darkened room, and so the device was called a camera obscura ‘dark chamber’. When the new science of photography developed in the 19th century, using the basic principle of the camera obscura, camera was applied to the picture-forming box.

dun: dun: English has two words dun. The colour adjective, ‘greyish brown’ [OE], comes ultimately from Indo-European *donnos, *dusnos, which is also the source of English dusk. The now rather dated noun, ‘debtcollector’ [17], is an abbreviation of dunkirk, a 17th-century term for a ‘privateer’, a privately owned vessel officially allowed to attack enemy shipping during wartime.

It was originally applied from such privateers that sailed from the port of Dunkirk, on the northern coast of France, to attack British ships, and its connotations of unwarranted piracy soon spread metaphorically to one who was constantly importuning for the repayment of his loan.
=> donkey, dusk, obfuscate

sycophant (n.): 1530s (in Latin form sycophanta), "informer, talebearer, slanderer," from Middle French sycophante and directly from Latin sycophanta, from Greek sykophantes "false accuser, slanderer," literally "one who shows the fig," from sykon "fig" (see fig) + phainein "to show" (see phantasm). "Showing the fig" was a vulgar gesture made by sticking the thumb between two fingers, a display which vaguely resembles a fig, itself symbolic of a vagina (sykon also meant "vulva"). The modern accepted explanation is that prominent politicians in ancient Greece held aloof from such inflammatory gestures, but privately urged their followers to taunt their opponents. The sense of "mean, servile flatterer" is first recorded in English 1570s.
The explanation, long current, that it orig. meant an informer against the unlawful exportation of figs cannot be substantiated. [OED]
