The spelling of the word "Phasel" can be explained using IPA phonetic transcription. The initial "Ph" sound represents the voiceless labial-velar fricative /f/, while the "a" sounds are pronounced as the low front unrounded vowel /æ/. The "s" is pronounced as the voiceless alveolar fricative /s/, and the final "el" sound represents the glide /əl/. Therefore, the correct IPA transcription of "Phasel" would be /ˈfeɪ.zəl/. It's important to pay attention to IPA symbols to ensure proper pronunciation of words.
