Slang

  • noun money, wealth. In the 18th century wedge specifically referred to silver, which criminals melted down and reconstituted as ‘wedges’ (ingots or bars). The term was used throughout the 20th century by working-class speakers, including street traders and criminals. Perhaps unconsciously influenced by wad and ‘edge’, the word has enjoyed a renewed popularity, like most of its synonyms, in the money-conscious environment of the 1980s.
