type of horse, large and stout but relatively free in action, by 1875, from French Percheron, adjective formed from le Perche, region south of Normandy where horses were bred that were strong, light, and fast.
early 15c., tenacite, "quality of holding firmly," from Old French ténacité (14c.) and directly from Latin tenacitas "an act of holding fast," from tenax (genitive tenacis) "holding fast, gripping, clingy; firm, steadfast," from tenere "to hold" (from PIE root *ten- "to stretch"). The PIE root produced two Latin verbs, tenere "to hold, grasp," and tendere "to stretch" (as in tend (v.1)), which perhaps is from an inflected form in the PIE verb. Both Latin verbs have past participle tentus.
1560s, "fix securely (a driven nail) by bending and beating it back," a variant of clench (q.v.). The sense of "settle decisively" is first recorded 1716, from the notion of "clinching" the point of a nail to keep it fast. Boxing sense is from 1860. Related: Clinched; clinching.
1744, "ropes, etc., by which a floating thing is confined or made fast," from mooring. Figurative sense of "that to which anything is fastened or by which it is held" is by 1851.
