What does neutered mean?
Neutered means deprived of the ability to reproduce, usually as a result of a veterinary procedure such as castration or sterilization. It is frequently used with animals, particularly cats and dogs, in discussions of adoption, animal welfare, breeding, and population control. The word can also be used figuratively for making a proposal, institution, argument, or other thing unable to function as intended; for example, a committee may neuter a plan by removing its essential features. In the reproductive sense, neutered is a direct and precise term, whereas sterilized is often used more broadly. The expression derives from the Latin neuter, meaning “neither,” which referred to a grammatical gender distinct from masculine and feminine.

Where does neutered come from?
The word comes through English neuter, a grammatical term inherited from Latin neuter, meaning “neither” or “unsexed.” In English, neuter has long been used for animals deprived of reproductive function. The form neutered developed as the past tense and participle of the verb neuter, and its figurative use for making something ineffective is a later extension of that meaning.
