The spelling of the word "art guilty" might seem a bit peculiar at first glance. However, it can be explained using the International Phonetic Alphabet (IPA). In IPA, "art" is pronounced as /ɑrt/, with the "r" being pronounced heavily. "Guilty," on the other hand, is pronounced as /ˈɡɪlti/, with a hard "g" and a "t" sound at the end. So when combined, "art guilty" becomes /ɑrt ˈɡɪlti/, with a distinct separation between the two words. While it may not be a common phrase, the spelling is easily explained by its pronunciation in IPA.
