The spelling of the word "cuc" can be explained phonetically using the International Phonetic Alphabet (IPA). This four-letter word consists of only one syllable pronounced as /kʌk/. The first sound, /k/, is a voiceless velar plosive, produced by blocking the air in the back of the mouth before releasing it suddenly. The second sound, /ʌ/, is a mid-central vowel sound pronounced with the tongue in a neutral position, neither high nor low. The final sound, /k/, is the same sound as the first.
