Forms: late Middle English repulsioun, late Middle English– repulsion, 1500s repulsyon, 1500s repultion; also Scottish pre-1700 repulsioun.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French repulsion; Latin repulsion-, repulsio.

Etymology: < Middle French repulsion (French répulsion ) action of repelling (14th cent.), action of seeing someone off, or forcing someone back (1432; 19th cent. in sense ‘aversion, disgust’) and its etymon post-classical Latin repulsion-, repulsio action of rejecting, refutation (5th cent.), (in medical context) action of driving away or expelling (13th cent. in a British source) < classical Latin repuls- , past participial stem of repellere repel v. + -iō -ion suffix¹. Compare repulse n., repulse v., repel v.

†1. Repudiation of a wife by her husband; divorce. Cf. repudiation n. 1. Obsolete. rare.
