dais: [13] Ultimately, dais and disc are the same word. Both came from Latin discus ‘quoit’, which by medieval times had come to mean ‘table’ (see DESK). Its Old French descendant was deis, which was borrowed into Middle English as deis. It died out in English around 1600, but it survived in Scottish English, and was revived in England by antiquarians, its spelling based on the modern French form dais. Historically it is a monosyllabic word, and the modern two-syllable pronunciation represents an attempt to render the unfamiliar French word.
