The spelling of the word "Ridenhour" can be confusing due to the presence of the letter "h." However, when using the International Phonetic Alphabet (IPA) to transcribe this word, the spelling becomes clearer. The IPA for "Ridenhour" is /ˈraɪdən.aʊər/, which indicates that the word is pronounced with a long "i" sound followed by the syllables "den" and "hour." The "h" in "hour" is silent, as is common in English words like "honor" and "hourglass."
