The spelling of the word "POIL" can be a bit tricky. The IPA phonetic transcription for "POIL" is /pɔɪl/, which indicates that the first syllable is pronounced with the "oi" diphthong, as in "voice" or "coin", and the second syllable is pronounced with a long "eel" sound, as in "peel" or "feel". It is important to remember to use the "oi" diphthong instead of a simple "o" sound, as this can significantly alter the meaning of the word.
