'communitarian' originates from the Latin word 'communitas,' meaning 'community,' combined with the suffix '-arian,' indicating a person who advocates or supports a particular principle.

'Communitas' transformed into the English word 'community,' and eventually the term 'communitarian' was coined to describe someone who supports community values.

Initially, it meant 'pertaining to a community,' but over time it evolved to include the advocacy of community values and principles.
