Keep an eye out for (5)
I believe the answer is:
await
'keep an eye out for' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for await that I've seen before include "Look for; be in store" , "Expect, anticipate" , "Remain in expectation for (an occurrence)" , "To be in store for (someone)" , "Look for (something to happen)" .)
