The word "clenge" seems like an unusual spelling, but it can be explained using the International Phonetic Alphabet (IPA). The "cl" sound is represented by the IPA symbol /kl/. The "e" at the end of the word is pronounced as a schwa sound, represented by the symbol /ə/. Therefore, "clenge" is pronounced as /klɛnʤə/. However, it is worth noting that this spelling is not commonly used in English, and the more standard spelling is "cleanse".
