IPA: /ˈɡɛldər/
KK: /ˈɡɛldər/
A person who performs the act of castrating animals, particularly male ones.
The gelder was called to the farm to help with the livestock.
The word 'gelder' originates from Middle English 'gelder' (meaning a gelded animal), which comes from the Old English 'gieldan' (meaning to pay or to yield). The term specifically refers to a castrated male animal, particularly in the context of livestock.
Think of 'yielding' or 'paying' attention to the fact that a 'gelder' is an animal that has been castrated, which is a form of yielding its reproductive capability.
