The action of moving something by turning it over and over, or a continuous rattling or rumbling sound.
From Middle English, derived from the verb 'roll' plus the suffix '-ing'. The word evolved from Old French 'roler' meaning to roll or revolve, ultimately from Latin 'rotulus' meaning a small wheel.
While most people now associate this word with J.K. Rowling, the author's surname actually comes from this old English word describing a rolling motion or sound. The name was originally occupational, likely referring to someone who worked with rolling mills or made continuous rumbling sounds in their trade.
