Etymology: The word's core idea is simply "a place where one thing touches or abuts another." Its root verb, "abut," comes from Old French "abouter," meaning to join at the end or to border on, built from "a-" (toward) and "bout" (an end or extremity). English took the noun "aboutement" from French, and the word was first recorded in 1644 with that general sense of two things meeting end to end. The architectural meaning arrived later. Its engineering sense is first attested in 1793, when it came to name the massive masonry at the ends of a bridge or arch that receives the thrust of the structure and carries it down to the ground. The word thus moved from describing any shared boundary to describing a specific, load-bearing piece of stone.
