Blame the dutch and early New Yorkers for the confusion surrounding how Santa Claus got his name.
The Dutch called Saint Nicholas “Sint Nikolass.”
When they colonized what is now New York City, the hard-edged New Amsterdam accent rendered it “Sinterldass.”
When the Dutch were driven out by the English and high rents, the name was Anglicized to “Santa Claus.”
Some people Santa is Spanish for “female saint”.
Santa Clause comes from the North Pole and brings gifts to the homes of the good children during the overnight hours of Christmas Eve.
Santa lives with his wife Mrs. Claus, a large number of magical elves, and at least eight or nine flying reindeer.
