The spelling of the phrase "most canceling" can seem confusing due to the multiple ways in which the letter "l" can be pronounced in English. However, the correct pronunciation is /məʊst kæns(ə)lɪŋ/, with the "l" in "canceling" pronounced as a clear /l/ sound. This word is spelled with a single "l" after the letter "n", as opposed to a double "l" as is commonly seen in British English spellings. It is an example of how phonetic transcription can help clarify spelling and pronunciation.
