intervening

The word "intervening" has a clear narrative of movement into a space between. It originates from the Latin intervenire, a compound of inter- ("between") and venire ("to come"). The literal sense was "to come between," describing a physical or temporal insertion. Over time, this concept broadened from describing a person who steps into a dispute to the more abstract adjective describing any event, period, or object that occupies a middle position, capturing the essence of something that "comes in between" two reference points.
