- noun an unprincipled, contemptible fellow. A word applied in the 19th century by privileged school pupils and students to their ‘common’ counterparts. It came to mean an often plausible but dishonourable male. Unknown to most of its users, the word is a short form of ‘caddie’, a Scottish and northern English dialect word meaning a junior or unskilled helper, itself from the french cadet.
