The Origin of Spay or Neuter
Monkeys or Monkies: Which Spelling Is Correct?
The word “spay” comes from Old French “espeier”, meaning to remove reproductive organs. It became part of the English veterinary language centuries ago.
The word “neuter” comes from Latin “neuter”, meaning “neither.” It was used in biology to describe organisms that cannot reproduce.
Over time, veterinarians began using both terms together as “spay or neuter” to describe sterilization procedures for all pets, regardless of gender.
This combined usage became standard in animal welfare campaigns, especially in shelters and veterinary medicine.
