The correct spelling of the word is "chipmunk" /ˈtʃɪpˌmʌŋk/. The "k" at the end of the word is sounded and gives a final stop to the word. The "m" is pronounced "m" and the "n" is pronounced "ŋ" which makes it nasal. The "ch" sound is pronounced with the tip of the tongue touching the hard palate. It is common for some people to misspell this word as "chipmuck" due to phonetic confusion. However, it is important to use the correct spelling to effectively communicate with others.
