Forms

interdire[1]

Etymology

It is borrowed from Latin interdīcō (“to forbid”), adapted after dire;[2][3][4][5][6][1] the religious sense comes from the Church Latin use “to forbid worship in a place or to a priest” (9th century).[2][3] The Latin verb is formed from inter- (“between”) and dīcō (“to say”);[3][7][8] Littré explains the sense from a legal use, “to invoke a law between parties”, hence “to forbid”.[3][7][8]

Old French had borrowed the verb in a more French form, entredire “to place under an interdict” (1174).[2][3][5][1] Compare Old Occitan entredire, Spanish entredecir and Italian interdire.[8]

Earliest recorded meaning

A document from Douai (about 1250, in a 16th-century copy) has it for “to forbid something to someone”.[2][3][7]

Semantic evolution

Its religious use for forbidding worship in a place appears in the Songe du Vergier (1376–78), and for a priest in Pascal (1656).[2][3] Before 1615 (Pasquier) it meant to suspend someone from his functions, and in civil law (Furetière, 1690) to deprive someone of the free management of his property.[2][3]

The adjective interdit “dumbfounded” (Corneille, 1634) gave the verb a sense “to throw into confusion” (Pascal, 1656), now rare, and s'interdire “to be disconcerted” (Molière, 1661), now out of use.[2][3] Montaigne (about 1590) uses it for making something impossible.[2] The slogan of May 1968, il est interdit d'interdire, reflects an absolute use.[3][9]
