IPA: /ˈnɛs.tlər/
KK: /ˈnɛs.tlɚ/
A person or thing that settles or rests snugly in a place.
The bird was a nestler, finding comfort in the cozy branches of the tree.
The word 'nestler' originates from the Old English 'nest' (meaning nest) combined with the suffix '-ler' (indicating a person who does something). A nestler is therefore a person who makes or tends to a nest.
Think of someone who 'tends to a nest' — that's what a nestler does, as they are involved in the care or creation of nests.
