Ostracize Has Greek Roots

In ancient Greece, citizens whose power or influence threatened the stability of the state could be exiled by a practice called ostracism. Voters would elect to banish another citizen by writing that citizen's name down on a potsherd. Those receiving enough votes would then be subject to temporary exile from the state. Ostracize originated with the meaning "to exile by the ancient method of ostracism," but these days it usually refers to the general exclusion of a person from a group at the agreement of its members.

ostracize

verb

os·​tra·​cize ˈäs-trə-ˌsīz 

ostracized; ostracizing

: to force to leave or refuse to include by ostracism

Etymology

from Greek ostrakizein "to banish by voting with pottery fragments," from ostrakon "shell, pottery fragment"

Word Origin

The ancient Greek word ostrakon had several meanings, including "a shell" and "a fragment of pottery." Such pottery fragments were used in ancient Athens as ballots in a particular kind of popular vote. Once a year the citizens would gather in the marketplace to decide who, if anyone, should be forced to go away temporarily for the good of the city. Each voter wrote a name on an ostrakon. If enough votes were cast against one person, then that person was sent away from the city, or ostracized.
