The spelling of the word "Sandigo" may seem confusing at first, but it can be easily explained using the International Phonetic Alphabet (IPA). The "s" is pronounced as [s], the "a" as [æ], the "n" as [n], the "d" as [d], the "i" as [i], the "g" as [ɡ], and the "o" as [o]. Therefore, the correct spelling of the word is "Sandigo", not "San Diego" as it may be commonly confused with. Remember to pay attention to the IPA phonetic transcription when spelling words correctly.
