The spelling of "runk" might seem unusual to some, but it actually follows the rules of the English language. In IPA phonetic transcription, it is spelled /rʌŋk/. The "u" represents the short vowel sound in "cup," the "n" is followed by a nasal consonant, and the final "k" is pronounced as a voiceless velar stop. While it may not be a common word, its spelling is consistent with other English words and can be easily pronounced when broken down phonetically.
