Caught in the act


Meaning
This idiom means to be discovered while committing a wrongdoing or secret activity, often implying guilt or embarrassment. It suggests being caught red-handed in the middle of an action, used in contexts of crime, mischief, or personal indiscretions.
Origin
The phrase likely dates to the 17th century, rooted in legal and theatrical language where ‘act’ referred to a deed or performance. An early use appears in a 1605 legal text: ‘Taken in the very act.’ By the 19th century, it was common in English, with Charles Dickens using it in *Oliver Twist* (1838) to describe a thief’s capture. Its dramatic imagery, tied to crime and exposure, ensured its popularity in journalism and literature.
