The noun is derived from Middle English strok, stroke (“blow from a weapon, cut”), from Old English strāc, from Proto-West Germanic straik, from Proto-Germanic straikaz (“stroke”), from Proto-Indo-European streyg- (“to rub, stroke; to shear; to strike”). Sense 3.5.2.2 (“the oblique, slash, or virgule (‘/’)”) is a contraction of oblique stroke, a variant of oblique which was originally used in telegraphy. The verb is derived from the noun.
