The Jèrriais word pais covers beans and peas (you need to specify which type of legume you mean). Pais au fou is beancrock. The word pais, like French pois and English pease, derives from Latin pisum (English pease, which survives in pease pudding and peasecods, was misinterpreted as a plural and a new singular was created: pea - see our post Turnips and paparazzi for similar reanalysis).But the Latin word pagus (a country district) has also come down to us as the word pais, meaning an area - most often these days in phrases and in placenames referring to a rocky area. In French it's ended up as pays, which we've adopted as our standard word for country: Jèrri est un p'tit pays (Jersey is a small country).
