interdigitate

Merriam-Webster's Word of the Day for January 16, 2010 is: interdigitate • \in-ter-DIJ-uh-tayt\  • verb : to become interlocked like the fingers of folded hands Examples: "The edges [of bridge expansion joints] often are shaped like combs, the teeth of one interdigitating with teeth of the other." (The Washington Post, January 14, 1998) 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.
