The spelling of the word "ottley" is somewhat complex, requiring an understanding of the IPA phonetic transcription system. In this system, the word is spelled /ˈɒtli/. The initial sound is represented by the symbol /ɒ/, which is similar to the "o" sound in the word "hot." The second sound is a "t" sound, represented by the symbol /t/. The final sound is represented by the combination of /l/ and /i/, which together sound like "lee." This complex spelling may be challenging for some English learners, but with practice, it can be mastered.
