In 1917, Ruth Putnam printed an exhaustive account of the work performed up to that time. She wrote that both Calafia and California most likely came from the Arabic word khalifa which means steward[6] or leader. The same word in Spanish was califa, easily made into California to stand for "land of the caliph" خلیف, or Calafia to stand for "female caliph" خلیفه .[7]
Maltese is another language that has a surprising amount of Arabic influence. The way they say their numbers is almost exactly the same as Arabic.
