nadsat
What does nadsat mean?
Nadsat is the fictional teenage slang spoken by Alex and his droogs in A Clockwork Orange. The name comes from the Russian suffix '-nadtsat' (-надцать), the equivalent of English '-teen' in numbers eleven through nineteen, so 'nadsat' literally signals 'teenage'.
Origin
Invented by Anthony Burgess for A Clockwork Orange (1962). The name derives from the Russian numeral suffix '-nadtsat', equivalent to '-teen'. Burgess described his aims in the essay 'Clockwork Marmalade' (1972) and built the argot mainly from Russian, with Cockney and Romani elements.
