Etymology

Origin of overlap

First recorded in 1685–95; over- + lap ²

Explanation

When things overlap, part or all of one thing covers part or all of the other, like roofing shingles or flat noodles in a lasagna dish. Not only can things overlap, but schedules can, too. If you accidentally schedule your doctor's appointment and your dentist appointment at the same time, they overlap, which is unfortunate because you can't be in two places at once. Philosophies and perspectives overlap when they share certain points or ideas in common.
