Many will argue that "Romany" and "Gypsy" require a specific genetic inheritance. The various spellings of "Diddikai" generally refer back to the Romany term for those without that inheritance who lived as the Gypsies did. In Ireland "Tinker" came to refer not specifically to those who mended pots and pans but to similar itinerants. "Pikey" came in the UK and Ireland as a catch-all for "Dids" and "Tinkers". "Traveller" (or in the US "Traveler") is now used to englobe all such and also to include "New Age Travellers" who came out of the 60s and 70s with a travelling habit of life.
