means To move by turning over and over on a surface, or the noun for anything that turns, tumbles, or curls up — from a list of names to a soft round of bread.

from From Old French 'roller' and Latin 'rotulare,' to roll, built on 'rotula,' a little wheel, the diminutive of 'rota,' wheel — the same spinning root that gives us 'rotate' and 'rotund.' A roll of bread is so called because it's rolled into shape; a roll-call lists names off a rolled-up sheet of parchment.
