Etymology

The term 'bandwidth' is a modern compound formed from two native English words. 'Band', originally meaning a strip or something that binds, was adopted in electronics to denote a specific range of frequencies bound together. 'Width', a measure of extent, quantifies the size of this range. Literally meaning "the width of a (frequency) band," the term's logic perfectly captures its technical definition. This concrete, spatial metaphor was then extended into computing to describe data transfer capacity and finally into colloquial use to represent the figurative capacity for mental or emotional processing.

Analysis

Structure: band (range) + width (measure) - band: From Old Norse 'band' (something that binds, a strip), via Proto-Germanic. In this compound, it functions as a noun meaning a defined range or strip of frequencies. - width: From Old English 'wīdu' (width), formed from 'wīd' (wide) + the noun-forming suffix '-th'. In this compound, it functions as a noun meaning the measurement of extent from side to side.
