The spelling of the word "tuitupou" may seem confusing, but it can be easily explained with IPA phonetic transcription. The correct pronunciation is [tuɪtuːpəʊ], which is a combination of t, u, i, t, u, u, p, and o sounds. The t, u, and p sounds are straightforward, but the double u and the o require some focus. The double u is pronounced like "oo," and the o is pronounced like "oh." So, "tuitupou" is pronounced "too-ee-too-poh" in English.
