Literally, ecology means the “study of houses”. The word was coined as ökologie by Ernst Haeckel, a German zoologist, in the 1870’s, based on the Greek word oikos. Although this means “house”, Haeckel was using it in the wider sense as “dwelling, habitat”. It was adopted into English soon after its coinage, originally as oecology which is similar to a Latin form.

The basic notion contained in the word economy is “household management”. It comes from Greek oikonomia, by way of French or Latin, and means the “steward of a household”. This was a compound noun formed from oikos, “house” and nemein, “manage”. The original sense “household management” was extended into English. It broadened out in the 17th century to the management of a nation’s resources, while the use of the derivative economics for the theoretical study of the creation and consumption of wealth dates from the early 19th century.
