The Etymology of Addict
Addict has a sharper original meaning than its modern softness suggests. In Roman law an addictus was a debtor formally adjudicated to a creditor: the judge had spoken (Latin dicere) the debtor over to (ad-) the creditor’s authority, and until the debt was discharged the addictus was effectively his to command — a kind of legal bond-servitude. The Latin verb addicere meant to declare over, deliver, assign. English borrowed it as a verb in the 1530s, in the literal sense of surrendering oneself or being delivered over to something — an art, a cause, a prince. The reflexive use ("to addict oneself to study") was at first morally neutral. The shift toward compulsive substance-use is surprisingly recent: the noun addict in the modern drug sense is recorded only from 1909, around the time international opium control was beginning. The Roman shadow remains: an addict is still, etymologically, someone bound over.
