Gyptians are a fictional ethnic group in the universe inhabited by Lyra Belacqua (His Dark Materials series by Philip Pullman.); they are roughly analogous to Gypsies. The name Gyptian, like Gypsy, is derived from Egyptian, the original English name for the Roma.
They are divided into large families, the heads of which make up the gyptians' Council, which in turn is ruled by the King of the Gyptians. Their culture, while widely spread, is tightly knit. Gyptian children are extravagantly loved and looked after instinctively by other members if they are to stray. Their ethnic group is small enough for all gyptians to know each other by name, yet large enough to supply 170 men to travel north on a rescue mission. Unlike real-world Roma, gyptians are water-travellers. They mainly live aboard boats traversing the canals and rivers of England. The gyptians' primary source of income appears to be through trading goods as they travel. Gyptians have a distinctive accent, and their vocabulary contains 'Fens-Dutch' words which appear to be generally unused by hegemonic society. Gyptians sometimes gather in a byanroping, meaning a summons or muster of families. They gather in the fens of Norfolk to discuss and decide important matters.
