The verb, especially sense 2 (“to scratch with the claws または fingernails”), is possibly related to Dutch schrammen (“to graze, scratch”)[1] and German schrammen (“to scratch, scrape”), from Late Middle High German schramm, schramme (“a graze, scratch”); further etymology unknown.
The noun is derived from the verb.
