aún
/aˈun/ · A1 · adv
still, yet
aún (accent) = still/yet; aun (no accent) = even. Accent = still waiting.
From Latin adhuc (to this point, until now). The accent splits it into two beats, a-ÚN, and that stressed form is the one meaning still or yet: aún no = not yet. Unaccented aun means even, as in aun así = even so.
