The word "koepp" has an unusual spelling that can be explained through phonetic transcription. In IPA, "koepp" would be pronounced as /kɛp/. The "k" is pronounced as usual, but the "oe" represents the sound /ɛ/, not the expected /oʊ/ sound. The double "p" indicates that the /p/ sound is pronounced twice as long. This unique spelling may cause confusion for readers unfamiliar with the word, but understanding its phonetic transcription can help clarify its pronunciation.
