MedicalGeneral

To remove the reproductive organs of an animal; specifically used for males.

While it can be a general term for both sexes, in veterinary practice, it almost always refers to the castration of males.

The story behind the word. In Latin, 'neuter' literally means 'neither' (ne- 'not' + uter 'either of two'). It originally referred to something that was neither masculine nor feminine, which is why we still use it in grammar for 'neuter' nouns.

A neutered animal is 'NEITHER' male nor female in terms of reproduction. Neither one nor the other.

Avoid using in human contexts unless referring to grammar or a lack of vigor, as it can be offensive.
