The spelling of the word "TANN" represents a phonetic challenge, as it does not conform to regular English pronunciation rules. The correct pronunciation of TANN is transcribed using the International Phonetic Alphabet (IPA) as /tæn/, which means that the "a" sound is short and pronounced as in "cat" while the "n" sound is a regular "n" sound. This word is typically used in the context of tanning leather and can be a source of confusion for those unfamiliar with the process.
