The spelling of "avai" may seem confusing at first, but it can be explained using the International Phonetic Alphabet (IPA). In IPA, "a" represents the "ah" sound, while "v" is pronounced as "vuh". The final "i" is pronounced as "ee". So, when pronounced phonetically, "avai" sounds like "ah-vuh-ee". This kind of word may be seen in regional or dialectic language use, so it is important to understand the phonetics of words to better understand their spelling.
