The story

Picture a Roman citizen leaving a duty undone: the Latin verb delinquere joined dē-, “completely,” with linquere, “to leave.” It could describe falling short or doing wrong, and its present participle, delinquens, named someone who had failed in an obligation. The word reached English through Middle French délinquant, becoming a noun by the late 15th century and an adjective around 1600. Linquere’s wider family includes relinquish and relic: one means to let go, the other is what has been left behind. A delinquent, at heart, is someone who has left an obligation behind—and then had to answer for it.

Modern usage

A young person characterized as a troublemaker or involved in minor offenses.
