deadman
C1-C2Technical/Formal (for device); Informal/Dramatic (for person).
Definition
Meaning
A physical device or structure designed to act as an anchor by using the weight of earth or other material, or a literal deceased person.
In railway or nautical contexts, a heavy object buried to secure a cable or anchor a structure; in general usage, often refers to a dead person, with contextual variation.
Linguistics
Semantic Notes
Its meaning is highly context-dependent, split between a specific technical object and a macabre or figurative reference to a corpse.
Dialectal Variation
British vs American Usage
Differences
In technical domains (rail, sailing, construction), the term is standard in both. As a term for a corpse, American usage is slightly more common in dramatic/crime contexts, while British English more often uses 'dead man' (two words) for the literal meaning.
Connotations
Technical use is neutral. The human reference carries strong, often grim or criminal, connotations.
Frequency
Low frequency overall. Technical use is niche; human reference is informal and used for dramatic effect.

Learning
Memory Aids
Mnemonic
Think of a 'deadman' as either a 'dead man' buried in the ground, or a device that does the job of a 'dead' (stationary, heavy) 'man' (object) holding something in place.
Conceptual Metaphor
INANIMATE OBJECT IS A (DEAD) HUMAN (the device metaphorically takes on the stationary, anchoring property of a buried body).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate technical 'deadman' as 'мертвец' - use 'якорь-мертвяк', 'мёртвый якорь'.
- The term 'deadman's switch' is a fixed phrase ('аварийный выключатель', 'выключатель мёртвого человека').
- Confusing the compound noun 'deadman' with the phrase 'a dead man' can lead to highly inappropriate translations in technical texts.
Common Mistakes
- Using 'deadman' in general conversation to mean a dead person (sounds oddly technical/dramatic).
- Misspelling as two words ('dead man') when referring to the technical device.
- Incorrectly assuming it's a verb or adjective (it's primarily a noun).
