What does jackleg mean?
Jackleg is an informal word for an ordinary sailor and, by extension, a worker who lacks the training of a skilled craftsman. Its best-known military and maritime sense treats a jackleg as a common sailor rather than an officer or specialist. The occupational sense commonly appears in expressions such as “jackleg carpenter” and denotes a worker whose work may be considered crude, rough, or inferior. The term can be dismissive when used by people who regard naval rank, craftsmanship, or formal training as important. As an adjective, it means characteristic of an ordinary sailor or an unskilled worker. Although now mainly encountered in historical writing, memoirs, and casual speech, jackleg was once a familiar dockside and workshop label. Its mild obscurity gives it a nostalgic quality, but its continuing use can offend because it implies a lack of status, competence, or polish.
