The spelling of the word "Gwineth" may appear confusing, but it can be explained using IPA phonetic transcription. The first sound is a voiced velar stop /ɡ/, followed by a voiced labiodental fricative /w/. The next sound is a voiced alveolar nasal /n/, and the vowel sound is a long /iː/. The final sound is a voiceless dental fricative /θ/. Therefore, "Gwineth" is spelled with a "G", "w", "i", "n", "e", "t", and "h", and is pronounced as /ɡwɪniθ/.
