IPA: /ˈɛdʒər/
KK: /ˈɛdʒər/
A tool used to cut or trim the edges of a lawn, often along sidewalks or curbs.
He used an edger to create a clean line between the grass and the sidewalk.
Edger → The word 'edger' is formed from 'edge' (from Old English 'ecg', meaning the border or margin of something) and '-er' (meaning a person who). An edger is a person or tool that creates or defines the edge of something.
Think of someone who works on the 'border' ('edge') of a garden or lawn, shaping it — that's what an 'edger' does.
