The spelling of the word "borsal" can be confusing. The IPA phonetic transcription of this word is /bɔːsəl/. The first syllable is pronounced as "bore," like the word for a hole in the ground. The second syllable is pronounced with a short "uh" sound, like the beginning of the word "up." The final syllable is pronounced with the "s" sound followed by a short "uhl" sound. Remembering the correct spelling and pronunciation of "borsal" can be tricky, but with practice, it can become second nature.
