The correct spelling of the word "[rəˈɡjɑno]" is "Ruggiano". The pronunciation of this word is characterized by the short "u" sound at the beginning, followed by a stressed syllable with a pure "g" sound (as in "goat"), and a final unstressed syllable with the "a" sound (as in "father"). The key to spelling "Ruggiano" correctly is to remember the double "g" in the second syllable, which indicates the hard "g" sound, rather than the soft "g" sound (as in "giant").
