The spelling of the word "riffe" may seem confusing at first glance. However, by looking at the IPA phonetic transcription, we can see that the double "f" is used to indicate a long "e" sound, as in "eve" or "evening." The "i" in the middle is pronounced like "ih," as in "sit" or "hit." Therefore, "riffe" is pronounced as "reef" with a longer "e" sound. Remembering the pronunciation of letters in words can help in mastering their spellings.
