[toledo_mudhen]

Anathema was originally used as a term for exile from the church, but evolved to mean "set apart, banished, denounced". The word comes from Koine Greek ἀνάθεμα,[1] meaning "something dedicated, especially dedicated to evil", from ἀνατίθημι (anatithēmi), meaning "offer as a votive gift", from ἀνά (ana), meaning "on", and τίθημι (tithēmi), meaning "I put". It originally meant something lifted up as an offering to the gods; it later evolved to mean:

to be formally set apart;
banished, exiled, excommunicated;
denounced, sometimes accursed

"Anathema" is a word used mainly in the English language to describe vehement disagreement to something. It is not a commonly used word, particularly in spoken language, perhaps because its meaning is often confused.
