Probably an alteration of British dialect scaddle (“‘to run off in a fright’”), from the adjective scaddle (“‘wild, timid, skittish’”), from Middle English scathel, skadylle (“‘harmful, fierce, wild’”), of Scandinavian origin; akin to Old Norse skathi (“‘harm’”). Possibly related to the Greek skedastios (“‘dispersion’”). (US) Possibly related to scud or scat.
Third person singular
