The word "Gwalstow" is a Welsh place name that can be spelled in various ways due to the complexity of Welsh orthography. Its pronunciation, however, can be transcribed using the International Phonetic Alphabet (IPA) as /ɡwælstəʊ/. This transcription indicates that the first syllable starts with a voiced velar stop "g" (/ɡ/), followed by the diphthong "wa" (/wæ/). The second syllable contains the fricative "s" (/s/) and the unstressed vowel sound "o" (/əʊ/) that ends with the voiceless dental stop "t" (/t/).
