sorcerer: [16] A sorcerer is etymologically a drawer of ‘lots’ – for the word comes ultimately from Latin sors ‘lot’ (source also of English sort). The plural sortēs was used for the ‘responses made by oracles’, and this formed the basis of the Vulgar Latin noun *sortārius ‘priest of the oracle’, hence ‘caster of spells’. It passed into English via Old French sorcier as sorser, which was later extended to sorcerer.

claque (n.)youdaoicibaDictYouDict
1860, from French claque "band of claqueurs," agent noun from claquer "to clap" (16c.), echoic (compare clap (v.)). Modern sense of "band of political followers" is transferred from that of "organized applause at theater." Claqueur "audience memeber who gives pre-arranged responses in a theater performance" is in English from 1837.
This method of aiding the success of public performances is very ancient; but it first became a permanent system, openly organized and controlled by the claquers themselves, in Paris at the beginning of the nineteenth century. [Century Dictionary]
