self-incrimination

The word is a modern legal compound built from distinct Latin and Germanic elements. The core, 'crimination,' originates from Latin criminari meaning "to accuse," itself from crimen (judicial decision, charge, crime). The prefix 'in-' intensifies the action, making it "to accuse or charge into." Prefixed with the Old English 'self,' the term literally constructs the concept of "accusing oneself into a charge." This logical, morpheme-by-morpheme construction directly yields the modern legal principle: the act of providing testimony or evidence that serves to accuse oneself of a crime.

Structure: self (own) + in (into) + crimination (accusation) self: Old English, meaning "one's own person." It functions as a prefix indicating reflexivity. in: Latin, a prefix meaning "in, into, on, upon." Here it intensifies or directs the action inward. crimination: From Latin criminatio (accusation, charge), derived from crimen (charge, indictment, offense). It functions as the core noun meaning "the act of accusing."
