ethics

The word 'ethics' traces its lineage to the ancient Greek concept of 'ēthos', which referred to the characteristic spirit, moral nature, or guiding beliefs of a person or community. This core idea of ingrained character and customary practice was systematized into a field of philosophical study by Aristotle, who wrote the 'Ethika' (the Ethics). The suffix '-ics', indicating an organized branch of knowledge, was appended, transforming the concrete notion of custom into the abstract, analytical discipline we know today. Thus, 'ethics' literally means the systematic study of character and customs, evolving from describing how people do behave to prescribing how they should behave based on reasoned principles.

Structure: eth (character, custom) + ics (systematic study) 'eth' originates from Greek 'ēthos', meaning character, custom, or disposition. 'ics' is a suffix from Greek '-ika', via Latin '-ica', used to denote a body of facts, knowledge, or principles related to a specific field.
