Borrowed from Late Latin anathema (“curse, person cursed, offering”), itself a borrowing from Ancient Greek ἀνάθεμα (anáthema, “something dedicated, especially dedicated to eternal damnation”), from ἀνατίθημι (anatíthēmi, “I set upon, offer as a votive gift”), from ἀνά (aná, “upon”) + τίθημι (títhēmi, “I put, place”). The Ancient Greek term was influenced by Hebrew חרם (herem), leading to the sense of "accursed," especially in Ecclesiastical writers.
