The spelling of the word "Gwynith" is unique and can appear confusing at first glance. However, when broken down phonetically, it becomes clearer. The word is pronounced /ˈɡwɪnɪθ/ (gwin-ith), with the "y" sound represented by the letters "wi". The "th" on the end is a dental fricative, which means air is forced between the tongue and teeth. This unusual spelling may come from Welsh origin, as the name "Gwyneth" is common in Wales.
