Etymology
the word 'abutment' originates from the late middle english period, derived from the old french verb 'abouter', meaning "to join end to end." this french term is a combination of the prepositional element 'a-' (to, at) and 'bout' (end). the core concept of an end or extremity meeting another is preserved in the modern engineering term. the latin-derived suffix '-ment' was added to form a noun indicating the concrete result or structure of the action of abutting. thus, the literal "act of bordering at an end" evolved into the specialized architectural and civil engineering term for a supporting structure that receives the thrust of an arch or bridge.
