Heading
chochum, chochem, or cochem, crafty; learned, wise, or a wise man. The term is found passim in early Hebrew literature, especially in the Book of Proverbs: 'A cochem will hear and increase learning' (Prov. i. 5). The slang sense has been introduced by the Whitechapel Jews. In Yiddish cochemer or cochem, the pronunciation of which is not dissimilar to cocum, means wisdom; cochum-*wirth = a thieves' landlord. (Cf., paragraph on German analogues.) Cocma is another Hebraism used by London Jews in a similar sense, but it has not made its way into slang.

German Analogues. Chochom, Chochem, Chochemer (which Hebraism is the root of the English cocum. Among German thieves who more frequently spell the word Kochem, Kochemer, the meaning is almost identical with that given it by their English brethren, except that the wisdom, profit, or luck, applies almost solely to the results of crooked ways and dealings. Chochom and its variants signify, therefore, the cunning, prudent, and successful vagabond; Chochem lehorre = a dangerous vagabond, one who is prepared for the worst; Chochem mechutten = a bad patron, a dangerous companion, a rogue of the worst type; Chochme = wisdom, cunning, circumspection, or the practice of swindling).
