IPA: /ˈblækˌlɛg/
KK: /ˈblækˌlɛg/
A term used to describe a person who works against trade unions, often taking the place of striking workers, or someone who cheats in card games.
The blackleg was criticized for crossing the picket line during the strike.
Blackleg is formed from "black" (from Old English "blæc", meaning dark or without light) and "leg" (from Old English "lǣg", meaning limb or leg). The term originally referred to a person with a dark or blackened leg, but it has also come to mean a scab or someone who works in place of striking workers.
Think of 'black' meaning dark and 'leg' referring to a limb — this helps you remember that 'blackleg' can refer to someone with a dark leg or a person who takes the place of others.
