the.com/stench
a smell with the confidence to enter a room before you do
means A strong, foul, offensive odor — the kind that lingers and overpowers.
from From Old English 'stenc,' meaning 'a smell or odor,' which in those days could swing either way — pleasant or vile. It's tied to the verb 'stincan' (to emit a smell), the same root that gives us 'stink.' Over the centuries the word soured: where 'stench' once described any scent, it narrowed to the bad ones, while its cousin 'stink' kept the verb-work. A relative of Dutch 'stank' and German 'Gestank,' all sharing a Germanic ancestor for the act of smelling — back when smelling something and being smelled were one and the same.
