The spelling of the word "poarch" can be confusing due to the similar pronunciation of the letters O and A in English. However, using the IPA phonetic transcription, "poarch" can be spelled as /pɔːrtʃ/ which shows that it starts with a low back rounded vowel sound /ɔː/ followed by a voiceless post-alveolar affricate /tʃ/. The correct spelling is "poarch" with an O, which refers to a small elevated platform, often used for hunting or observation purposes.
