environmentalist

The word 'environmentalist' is a modern construction built upon the older noun 'environment'. The journey begins with the Old French verb environner, meaning 'to surround', which itself is built from en- (in) and viron (a circuit or circle). This concept of encircling surroundings was nominalized in English as 'environ' (archaic) and later 'environment' in the 19th century, signifying the conditions and influences that surround an organism. The suffix '-al' was added to form the adjective 'environmental', pertaining to this surrounding context. Finally, the agent suffix '-ist', of Greek origin via Latin, was appended to create 'environmentalist', literally meaning 'one who practices or is concerned with that which pertains to the surroundings'. This neatly encapsulates the role of a person focused on the physical and ecological conditions that encircle and sustain life.
