Usage

What does euthanize mean? Euthanize means to painlessly put a person or animal to death.The decision to euthanize a person is usually made because they have a painful, incurable disease or condition which will cause them to die slowly and in great pain. Where it is legal, the dying person must consent to being euthanized and only a doctor or other permitted person is legally able to end that person’s life.With animals, the decision is usually left to the animal’s owner, with a veterinarian or other qualified person actually ending the animal’s life. Animals are also usually euthanized because they are in great pain that cannot be relieved any other way.Euthanize is also written as euthanatize. In British English, the spellings euthanise and euthanatise are also used.Example: A veterinarian sometimes has to euthanize an animal when they will otherwise suffer a painful death.
