What does culprit mean?
A culprit is the person responsible for a crime, offense, or act of wrongdoing — the one whose fault something is. The word also extends naturally beyond people to causes: when a machine breaks or a plan fails, journalists and ordinary speakers alike identify a faulty part, a bad decision, or even a nutrient as 'the culprit.' This figurative use gives the word great flexibility, letting it serve both in police reports and in lighthearted explanations of everyday mishaps. Connotations lean accusatory; calling someone the culprit asserts their guilt, so the term is best used once responsibility is reasonably established, or hedged with words like 'suspected.' Historically colorful, culprit entered English in the late seventeenth century from a contraction of the Anglo-Norman courtroom phrase 'culpable: prest' — 'guilty, and ready to prove it.' Its relatives include culpable, exculpate, and inculpate, all tracing back to the Latin noun culpa, meaning fault or blame. Few common nouns carry such a vivid legal pedigree into daily conversation.
A person who has committed a crime or other offense; the one responsible for wrongdoing.
"The culprit was identified by security footage within hours of the robbery."
The cause of a problem, fault, or undesirable situation, whether a person or a thing.
"A leaky valve proved to be the culprit behind the drop in water pressure."
This extended sense frequently applies to objects, substances, or abstract factors rather than people.
Standard plural; used when referring to multiple offenders or multiple contributing causes.
"Investigators believe several culprits were involved in the smuggling ring."
'Culprit' was never meant to be a word at all — it began as a fragment of a courtroom formula, 'culpable: prest,' meaning 'guilty, and ready to prove it.'

Etymology of culprit
Culprit entered English in the latter half of the seventeenth century, derived from the Anglo-Norman phrase 'culpable: prest,' the formula by which a defendant pleaded guilty while declaring readiness to prove the plea. The phrase contracted into the single hybrid word 'culprit,' which then took on independent life as a noun. Its deeper root is the Latin culpa, meaning fault or blame, which also underlies related English words such as culpable, exculpate, and inculpate.
How culprit is actually used
Standard register in both formal and everyday contexts. The extended sense — blaming an inanimate object or abstract factor as the 'culprit' — is common in journalism and casual speech ('salt is the real culprit'). It carries an inherently accusatory connotation, so use care when the responsibility is not yet established.
