bioethics

The term 'bioethics' is a modern compound, first used in the 1970s, that directly combines two classical roots to address contemporary dilemmas. The first element, 'bio-', originates from the Greek word 'bios', meaning 'life' or 'mode of life', which has been a productive prefix in scientific vocabulary since the 19th century. The second element, 'ethics', derives from the Greek 'ethikos', relating to character, which itself comes from 'ethos' meaning custom or habit. The compound's logic is transparent: it applies the established field of moral philosophy ('ethics') to the new and complex questions of life and death, health, and biological manipulation ('bio-') brought forth by modern medicine and biotechnology. Thus, it names the systematic study of right and wrong conduct within the sphere of the life sciences.

Structure: bio (life) + ethics (moral principles) - bio: From Greek 'bios' (life). A combining form meaning 'life' or 'living organisms'. - ethics: From Greek 'ethos' (character, custom). A noun meaning the moral principles that govern a person's behavior or the conducting of an activity.
