c.1200, "to stretch out, to send in various directions," probably from Old English -sprædan (especially in tosprædan "to spread out," and gesprædung "spreading"), from Proto-Germanic *spraidijanan (cf. Danish sprede, Old Swedish spreda, Middle Dutch spreiden, Old High German and German spreiten "to spread"), probably from PIE *sper- "to strew" (see sprout (v.)). Reflexive sense of "to extend, expand" is attested from mid-14c.
