verb curse or declare to be evil or anathema or threaten with divine punishment
originFrom anathema + -ize; the -t- is part of the root of the underlying Greek word ἀνάθεμα (anáthema) (albeit not visible in the nominative singular form), which also explains the plural anathemata and other derivations from anathema such as anathematic.
