Trundler → The word 'trundler' is derived from 'trundle' (from Middle English 'trundlen', meaning to roll or move in a circular motion) and the suffix '-er' (meaning a person who). A trundler is a person or thing that rolls or moves in a circular manner.
Imagine someone or something that 'rolls' — that's what 'trundler' means, a person or thing that rolls around.
