the.com/abutment
the unsung muscle that catches a bridge mid-fall and refuses to let go.
means The solid structure—usually of masonry or concrete—at the end of a bridge or arch that bears its weight and absorbs the horizontal thrust pushing outward.
from From 'abut,' meaning to touch end-to-end or border on, which came into English through Old French 'abouter'—'a-' (to) plus 'bout' (end), a relative of the word 'butt' in the sense of a blunt end. So an abutment is literally the thing the bridge butts up against, named for the very act of leaning hard into something solid. The '-ment' suffix turns the verb into the structure that does the work.
