the.com/euthanasia

means The deliberate ending of a life to stop suffering, typically for someone terminally ill or in unbearable pain.

from From Greek eu- ('good, well') plus thanatos ('death') — literally 'a good death.' The word entered English in the 1600s meaning simply a peaceful, easy end to life, with no medical intervention implied. It drifted over centuries toward its modern sense of deliberately hastening death, and in the 20th century picked up heavy, often painful political and ethical baggage that the gentle original Greek never carried.
