The word 'rundle' originates from Middle English 'rundel', which is a diminutive form of 'round' (from Old French 'rond', meaning circular or round). It refers to something small and round in shape.
Think of something small and round, as 'rundle' comes from 'round' — it helps you remember that a rundle is a little round object.
