IPA: /ˈfɔːlər/
KK: /ˈfɔlər/
A person or machine that causes something to fall, often used to refer to someone who cuts down trees.
The faller skillfully cut down the large oak tree.
The word 'faller' is derived from 'fall' (from Old English 'feallan', meaning to drop or descend) and '-er' (meaning a person who). A 'faller' is therefore a person who falls or causes something to fall.
Think of someone who 'drops' or 'descends' — that's what a 'faller' means, as it refers to a person who falls.
