köken: From Amphitruo, a comedy by the Roman playwright Plautus (c. 254 – 184 BC), in which doubling is the major theme: both the title character and his slave, Sosia, are doubled by the gods Jupiter and Mercury, in order to enable Jupiter to make love to Amphitruo's wife.
köken: Literally, “spat and expectorated”. Compare English spitting image, Galician cuspido (literally “spat”) and French tout craché (literally “totally spat”), which also equate likeness to spit.
