Etymology

Origin of skim

First recorded in 1425–75; late Middle English skymen, skemen, variant of scumen “to skim,” perhaps from Old French escumer “to remove scum”; see scum

Explanation

To skim is to remove something from the surface of a liquid. Some cooks skim the fat off of the top of their chicken noodle soup, others skim the cream off milk to make skim (or skimmed) milk. Cream is what you skim off the surface of milk, and if you don't like the whipped version, you might skim it from your hot chocolate. Another way to use the word skim is to mean "read quickly," like when you skim the newspaper, catching just the headlines as you search for the comics section. Skim has an Old French root, escumer, "remove scum," from escume, "scum." The "glance through a book" meaning came later, in the late 1700’s.
