Etymology

The word "interval" originates from Latin intervallum, combining inter ("between") and vallum ("wall" or "rampart"). Historically, it referred to the space between defensive walls in a military context. Over time, the meaning expanded metaphorically to denote any gap or pause—whether temporal (time between events), spatial (distance between objects), or musical (pitch difference). The logic reflects a progression from physical separation to abstract intervals.
