I am asking for the word “Palestinian”...when was that first used?The term "Palestine" first appeared in the 5th century BC when the ancient Greek historian Herodotus wrote of a "district of Syria, called Palaistinê" between Phoenicia and Egypt in The Histories. Herodotus applied the term to both the coastal and the inland regions such as the Judean mountains and the Jordan Rift Valley .
