Did You Know?
It probably won’t surprise you to learn that interdigitate comes from the prefix inter-, as in interlock, and the Latin word digitus, meaning "finger." Digitus also gave us digit, which is used in English today to refer to (among other things) the finger or toe of any animal. "Interdigitate" usually suggests an interlocking of things with fingerlike projections, such as muscle fibers or the teeth of an old-fashioned bear trap. The word can also be used figuratively to imply a smooth interweaving of disparate things, such as the blending of two cultures within a shared region.
