The word "antinonnin" has a complex spelling that can be explained through IPA phonetic transcription. It is pronounced as /æn.tiˈnɒn.ɪn/ and consists of four syllables. The first syllable "an" is pronounced with a short "a" sound, while the second syllable "ti" is pronounced with a short "i" sound. The third and fourth syllables "non" and "in" both have a short "o" sound followed by an "n" sound. The spelling of this word appears to be a phonetic invention, as it does not correspond to any established patterns or roots.
