The spelling of the word "bynes" can be explained using the International Phonetic Alphabet (IPA). Phonetically, "bynes" is pronounced as /baɪnz/. The first sound "b" is a voiced bilabial plosive, followed by the diphthong "ai" /aɪ/. The final sound "ns" is pronounced as a voiceless alveolar nasal followed by a voiceless alveolar fricative /nz/. This spelling can be confusing as the "y" and "e" can have multiple sounds, but in this case, they make the sound of a diphthong, /aɪ/.
