The word 'antum' is not a commonly used word. However, if we were to examine its spelling, it would be pronounced 'æntʌm' according to the International Phonetic Alphabet (IPA). The symbol 'æ' is pronounced as the 'a' in 'cat', 'ʌ' as the 'u' in 'hut', and 'm' as we usually would. It is important to understand the IPA because it helps with the accurate pronunciation of words, particularly in languages with varied phonemes like English.
