Why “insinew” is a great word

INSINEW — [Verb] To strengthen with, or as if with, sinews; to invigorate. From the English prefix in- (expressing inwardness or intensification) + sinew (a tendon, or source of strength). Unlike "fortify" (which suggests external bulwarks) or "animate" (which implies the spark of life), to insinew is to weave tensile resilience into the very fiber of a being. It is the patient repetition of a craft that turns fumbling skill into unbreakable habit; the way scar tissue knits itself tougher than the original skin; the deep, centering breath that threads new cords of steadiness along the spine—the quiet, cellular work of becoming difficult to snap.
