The spelling of the word "am invented" is straightforward if one understands the International Phonetic Alphabet (IPA) transcription system. The word begins with the vowel sound /æ/ as in "cat," followed by the consonant sound /m/ as in "mom." The diphthong sound /ɪ/ as in "sit" takes the place of the traditional letter i, making the spelling unique. The word then ends with the voiced dental fricative /ð/ as in "this," followed by the voiced alveolar plosive /d/ as in "dog." With IPA phonetic transcription, the spelling of "am invented" becomes more understandable.
