IPA: /ˈpruːnər/
KK: /ˈpruːnər/
A person who cuts away dead or overgrown branches from plants or trees to encourage healthy growth, or a tool used for this purpose.
The gardener used a pruner to trim the rose bushes in the spring.
Pruner → It is formed from "prune" (from Old French *prune*, meaning dried plum) and the suffix "-er" (meaning a person who). A pruner is a person who prunes, or cuts back, plants or trees, often to promote growth or remove dead parts.
Think of someone who 'cuts back' plants — the word 'pruner' comes from 'prune', which means to trim, and '-er' indicates a person doing the action.
