The word "fasulo" is spelled with four letters and is pronounced as [fəˈsuːloʊ]. The initial letter, "f", is the voiceless labiodental fricative sound which is created by blowing air between the lower lip and the upper teeth. The following two letters, "a" and "s", are pronounced with their standard phonetic values. The final letters, "u" and "lo", are pronounced with the back open rounded vowel and the voiced alveolar lateral approximant sound respectively. The spelling of the word reflects its Italian origin.
