Up to now, and not now but possibly later. The word that holds a door open while reporting it closed.
Old English gīeta / gēt (up to now, still, nevertheless); the Old English form is secure but its own further ancestry is not — no confident cognates survive outside English, so the word's history before Old English is unknown.
A small word doing two jobs at once — reporting that something has not happened, without closing the door on it happening later. It says what is not yet true without saying it never will be.
