The word "alochia" may seem tricky to spell, but it's actually quite straightforward once you understand its origin. This word comes from the Greek word "allokia", which means "otherness" or "difference". In IPA phonetic transcription, "alochia" is spelled /əˈləʊkiə/, with the stress on the second syllable. The tricky part of this word lies in the "ch" sound, which in IPA is represented by /k/. This is because the letter chi (χ) in Greek is pronounced like "k".
