ostracism

The word 'ostracism' originates from the ancient Athenian democratic practice of voting to banish a citizen for ten years. Votes were cast by inscribing a name on a potsherd or tile, an ostrakon. The literal meaning of the Greek root ostrakon was a hard, brittle object like a shell, tile, or piece of broken pottery. Over time, the specific political procedure faded, but the term endured, evolving from the concrete act of casting a shell-vote to the abstract modern concept of formal or social exclusion. Thus, the journey is from a physical shell used in voting to the generalized practice of banishment it represented.
