lame-duck

The term "lame duck" originated in 18th-century British stock exchange slang, referring to a defaulter on debts who could not meet financial obligations, waddling away like an injured bird. This imagery of ineffectiveness was later adopted into American political jargon in the 19th century. It specifically came to denote an elected official, especially a president or congressperson, whose power is diminished because they have not been re-elected but must continue serving until their successor is sworn in. The compound perfectly encapsulates the concept through the metaphor of a wounded animal, combining 'lame' (impaired in movement) with 'duck' (a common bird), to symbolize compromised authority and limited capacity for action.

It is of Germanic origin. In this compound, it functions as a noun, but its literal meaning is secondary to its role in the established idiom.
