fascicle
noun
Did you know?
Fascicle, which has been a part of our language since the 15th century, is one of a bundle of words derived from Latin fascis, meaning "bundle." In book publishing, "fascicle" and its variants "fascicule" and "fasciculus" can all be used for one of the installments of a voluminous work; "fasciculus" can also be used for a bundle of anatomical fibers. "Fasciitis" is an inflammation of a "fascia," which is a sheet of tissue connecting muscles. You can also have a case of "fasciculation," or muscular twitching. Other descendants of "fascis" include "fasces" (a bundle of rods and an ax borne before ancient Roman magistrates as a badge of authority) and "fascine" (a long bundle of sticks of wood bound together).
