Forms: 1600s mitrall, 1600s mitrial, 1600s mytrall, 1600s– mitral, 1700s mytrale.

Origin: Formed within English, by derivation. Etymons: mitre n.¹, -al suffix¹.

Etymology: < mitre n.¹ + -al suffix¹.With mitral valve at sense A. 2a, compare French valvule mitrale (1673), post-classical Latin mitrales valvulae , plural (see quot. 1693 for mitral valve n. at Compounds).
