Origin of the term coleslaw, copied from culinarylore.com.

"The term coleslaw came from the Dutch term koolsla, meaning cabbage salad. The kool part is the Dutch word for cabbage and the sla part is a Dutch abbreviation of the word salade. In the late seventeenth and early eighteenth centuries, Dutch settlers flooded into New York, so much so that the city was originally called New Amsterdam. They brought with them their recipe for chilled cabbage salad, which today is a mixture of the shredded vegetable with mayonnaise, salad dressing, sour cream or buttermilk with vinegar, sugar and other seasonings added."
