The spelling of the word "shuler" may seem confusing at first, but it can be easily explained using IPA phonetic transcription. The "sh" sound is represented by the symbol /ʃ/, followed by a short 'u' sound /ʌ/ and an 'l' sound /l/. The final 'er' sound is often represented by the symbol /ər/, which indicates a schwa sound followed by an 'r' sound. Therefore, the correct spelling of the word "shuler" is: /ʃʌlər/.
