the thing standing in your way until someone decides it's a doorway instead
means Something — physical, social, or abstract — that blocks passage, progress, or access from one side to another.
from From Old French 'barriere,' a fence or obstruction, built on the root 'barre' — a bar, beam, or pole laid across a way. The same 'barre' that gives us 'bar,' 'barricade,' and 'embargo': the whole family descends from the humble image of a stout length of wood thrown across a path to say 'not past here.' English borrowed it in the Middle Ages, and we've been bumping into versions of that bar — wooden, then concrete, then bureaucratic — ever since.
