(third-person singular simple present speels, present participle speeling, simple past and past participle speeled)
From Old Scots speill (“to climb”), of obscure origin. From or akin to Old Scots spelare (“acrobat, tumbler”). Probably from Middle Dutch spelen (“to play, walk a tight rope, do gymnastic tricks, juggle, perform as an actor or clown”), see spiel. Alternately, representing a continuation of Old English spilian (“to play”).
