IPA: /ˈmʌz.lər/
KK: /ˈmʌzlɚ/
A person who puts a muzzle on an animal to prevent it from biting or barking.
The muzzler carefully placed the muzzle on the dog before the vet visit.
Muzzler → The word originates from the verb 'muzzle' (from Middle English *muzzle*, meaning to cover the mouth of an animal) combined with the suffix '-er' (meaning a person who). A muzzler is a person or device that puts a muzzle on something, typically to prevent it from biting or speaking.
Think of someone who 'covers the mouth' ('muzzle') of an animal or person, and the '-er' indicates that this is a person doing the action.
