dead horse
B2Informal, Idiomatic
Definition
Meaning
An issue, topic, or effort that has been exhausted, is no longer relevant, or yields no further benefit.
A subject or problem that has been discussed or dealt with so much that further discussion is pointless. The phrase often refers to a debt already paid or work already compensated for.
Linguistics
Semantic Notes
Primarily used as a noun phrase in idioms ('flogging a dead horse', 'work for a dead horse'). It is a metaphor for futility. The 'debt' sense is now dated.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'мёртвая лошадь'; it will be misunderstood. The correct equivalent idiom is 'носить воду решетом' (to carry water in a sieve) or 'толочь воду в ступе' (to pound water in a mortar).
- The idiom 'flog a dead horse' translates to 'бить лежачего' (to hit someone who is already down) or the phrases above.
Common Mistakes
- Using 'dead horse' as an adjective without the idiom structure (e.g., 'That's a dead horse idea' is unnatural).
- Confusing it with 'beating a dead horse', which is the American variant of 'flogging'.
- Using it to refer to a literal deceased animal, which is not the idiomatic meaning.
