The spelling of the word "Hiddink" is often confusing due to its unusual pronunciation. In IPA phonetic transcription, it is /ˈhɪdɪŋk/. The first syllable is pronounced with a short "i" sound, followed by a "d" sound in the second syllable. The third syllable has a clear "ing" sound, and the final syllable is pronounced with a short "i" sound and a silent "k." Although it may be difficult to remember the correct spelling, practicing the correct pronunciation can help with recognizing the correct spelling in the future.
