magnetn.

Brit.

/ˈmaɡnᵻt/, U.S.

/ˈmæɡnət/

Forms: late Middle English–1600s magnete, late Middle English– magnet, 1500s mangnet.

Origin: A borrowing from Latin; probably modelled on a French lexical item. Etymons: Latin magnēt-, magnēs.

Etymology: < classical Latin magnēt-, magnēs (see magnes n.), probably influenced by Anglo-Norman magnete, Old French, Middle French magnete, manete, mangnete.Compare Spanish magnete (c1250; now archaic), Italian magnete (1354), Portuguese magnete (17th cent.); Middle Dutch, Dutch magneet , early modern German magnet , magnete (German Magnet ; also Middle High German magnes : compare magnes n.), Danish magnet , Swedish magnet : the corresponding word in French is aimant , cognates of which also occur in the same sense in Spanish and Portuguese (see aymont n., adamant n. and adj.), while Italian has calamita alongside magnete. The form magneten which occurs once in Old English is after the post-classical Latin accusative singular magneten (6th cent.):OE Lapidary 14 Sum stan hatte magneten; gif þæt isern bið bufan þæm stane, hit wyle feallan on þane stan; gyf se stan bið bufan, hit wile springan up ongean þæne stan. The form magnetis which occurs once in Lydgate is probably after the classical Latin genitive singular magnētis:a1456 ( J. Lydgate Minor Poems (1934) ii. 696 Where Bellona haþe bylt a stately hoolde..Of harde magnetis and dyamandes ryche.
