'Arao' is spelled using the IPA pronunciation as /əˈrɑʊ/. This word can be tricky to spell correctly due to the presence of two vowel sounds, namely the schwa /ə/ and the diphthong /aʊ/. The schwa is a short and unstressed vowel, while the diphthong is a combination of two vowel sounds that glide together. When writing 'arao', it's important to remember to use both 'a' and 'o' for accurate phonetic representation.
