어라

Blunt plain command

The bare command form, with no politeness attached: wait for us, fly, congratulate me, do it. Because it is short and punchy it fills on-screen captions and titles in these lines, including the Korean name for 'Where's Waldo?'. Aimed at a real person it only works with close friends, juniors, or as a shout; use 세요 for anyone else. 어 on its own is the softer casual version of the same order.

Register: blunt plain command; also captions and titles
