The spelling of the word "came snuff" may seem unusual to some, but it is actually a phonetic representation of a Southern American English pronunciation of the phrase "came enough." In IPA phonetic transcription, this would be written as /kem əˈnʌf/. The sound change from "enough" to "snuff" can be attributed to the Southern Vowel Shift, a phenomenon where certain vowel sounds shift in pronunciation in Southern American English dialects.
