The correct spelling of the name is "Antoinette" /ænˈtwɑːnɛt/. The first syllable is pronounced "an" as in "can" /kæn/, followed by "twah" /twɑː/. The last syllable is pronounced "net" as in "net" /nɛt/. The incorrect spelling of the name as "Anteunette" likely comes from a misheard pronunciation of the "oi" diphthong in "Antoinette" as "eu". Proper spelling and pronunciation of names is important for clear communication and proper respect for individuals.
