ostracize
UK: ˈɒstrəsaɪz | US: ˈɑːstrəsaɪz
vt. to exclude someone from a group or society by general consent
vt. to banish or exile someone, especially for political reasons
The word traces back to ancient Athenian democracy, where citizens would vote by scratching names on pottery shards (ostraka). If a person received enough votes, they were banished for 10 years—a practice called ostrakismos. Over time, "ostracize" evolved into its modern meaning of social exclusion.
