Corradiate is not a commonly used word, and its spelling can be quite confusing. However, its pronunciation can be explained using IPA phonetic transcription as /kəˈrædiˌeɪt/. This suggests that the stress falls on the second syllable, and the word is made up of four syllables in total. The "c" at the start of the word is pronounced as a "k" sound, and the "rr" in the middle should be pronounced as a single "r" sound, like "radiate".
