The spelling of the word "Quayd" is quite interesting. It is actually a variant of the word "quaid", which means leader or chief. The spelling is based on the Irish Gaelic pronunciation, with the "q" representing the sound of the Gaelic "c". In IPA phonetic transcription, the word would be spelled /kwede/. The spelling may seem confusing or unfamiliar to English speakers, but it reflects the word's origins in Irish language and culture.
