The correct spelling of the word "ETHYLEPA" is not recognized in any language, and therefore cannot be explained using the International Phonetic Alphabet (IPA). It is possible that the intended word was "ethylene," which is pronounced /ˈɛθəliːn/ with the stressed syllable "eth" pronounced as /ɛθ/ and the unstressed syllable "lene" pronounced as /liːn/. It is important to use correct spelling and pronunciation in communication, as errors can lead to misunderstandings or confusion.
