Definition
Meaning
A detective story or crime drama in which the primary focus is the motive for the crime rather than who committed it or how.
A subgenre of mystery or crime fiction that explores the psychological, social, or situational reasons behind a criminal act. It can also refer to any narrative, historical analysis, or investigative report that focuses on uncovering the underlying causes of an event.
Linguistics
Semantic Notes
A blend of 'why' + 'whodunnit'. Unlike a traditional 'whodunnit', the identity of the perpetrator may be known from the start, shifting suspense to the psychological or sociological 'why'.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. The spelling 'whydunit' (without double 'n') is slightly more common in the US, while 'whydunnit' (with double 'n') is the standard UK spelling, mirroring 'whodunnit'.
Connotations
In both varieties, the term connotes a more psychological, character-driven, or socially analytical approach to crime fiction than the classic puzzle mystery.
Frequency
Equally rare in both dialects, primarily used by critics, writers, and enthusiasts of the mystery genre.

Common Pitfalls

- Do not translate literally as "почемудетектив". It is a fixed genre term. Use descriptive translation: "детектив, раскрывающий мотив преступления", or transliterate: "уайданнит" in specialised contexts.
Common Mistakes
- Incorrect spelling: 'whydunit' (acceptable variant, but less common in UK), 'why-dunnit', 'whydunit'.
- Confusing it with 'whodunnit'.
