Merlons are sometimes pierced by narrow, vertical embrasures, or tooth-like slits designed for observation and fire. The space between two merlons is called a crenel, and a succession of merlons and crenels is a crenellation. Crenels designed in later eras for use by cannons were also called embrasures.

==Etymology== The term merlon comes from French [1704], adapted from the Italian , possibly a shortened form of , perhaps connected to Latin ("two-pronged pitchfork"), or from a diminutive , from or (a wall). An alternative etymology suggests that the medieval Latin (mentioned from the end of the 10th century) functioned as a diminutive of Latin , "blackbird", expressing an image of this bird sitting on a wall.
