The spelling of the word "ex curses" is fairly straightforward. It is spelled "ex" followed by the plural form of the noun "curse". The IPA phonetic transcription for this would be /ɛks ˈkɜrsəz/. The first syllable of "ex" is pronounced with the short "e" sound, the "x" is pronounced with a voiceless velar fricative (similar to the "ch" in the German word "nicht"), and the second syllable of "curses" is pronounced with the "er" sound followed by the "s" sound.
