The correct spelling of the word "Etern" is actually "Eton". The IPA phonetic transcription of this word is /ˈiːtən/. The "e" is pronounced as a long "e" sound, while the "t" and "o" are pronounced as separate syllables with a slight pause between them. This word is often misspelled due to its resemblance to the French word "etern", meaning eternal. However, in English, it is spelled with just one "r" and is pronounced differently.
