Etymology

Origin of ajar1

1350–1400; Middle English on char on the turn; see a- 1, char 3

Origin of ajar2

1545–55; for at jar at discord; cf. jar 3 (noun)

Explanation

The adjective ajar describes something that is slightly open. A door that has been left ajar is easily pushed open by the wind or a nosy person. To correctly pronounce ajar, say "uh-JAR." People in a hurry leave drawers and cabinet doors ajar, or hanging open. If a chime starts ringing when you start a car, a door or the trunk may be ajar. Check that everything is securely closed before taking off. But don't describe a mouth that is open in surprise as ajar. A better word choice is agape.
