Roller

Roller

Noun · /ˈrəʊlə/ · something that rolls — from tools to waves to hairstyles

Definition

A roller is any cylindrical object designed to roll, or anything that performs a rolling action. The word is broad and contextual: a paint roller applies paint to a wall; a road roller compresses tarmac; a hair roller shapes curls; a roller in the ocean is a long, swelling wave. The core idea is always the same — a rounded form moving across a surface or wrapping around it.

Origin

From the verb roll, which traces back through Old French roller to Latin rotulare — from rota, meaning wheel. The suffix -er in English creates the agent noun: the thing that rolls. The word has been in continuous use since the fifteenth century and has expanded into dozens of compound forms as new technologies emerged — steamroller, paint roller, roller skate, roller coaster, roller blind.
