English
anathematize
From 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.
Formed from anathema + -ize
Ancient Greek ἀνατίθημι ‘to set upon, offer as a votive gift’
Ancient Greek ἀνάθεμα ‘something dedicated, especially dedicated to…’
Late Latin anathema ‘curse, person cursed, offering’
English anathema
Today it means
verb To cause to be, or to declare as, an anathema or evil.
