The word "kuchean" is a rare term that is not typically found in dictionaries. It appears to be a variant spelling of the word "Kutchan," which refers to a people from northwest China. The spelling suggests that the first syllable should be pronounced with a "k" sound and the second syllable with a "ch" sound, represented in IPA phonetic transcription as /ˈkuːtʃiːən/. However, since this word is not commonly used, it is important to double-check the spelling and pronunciation before using it in any context.
