Slip when I run to escape large creature (5)
I believe the answer is:
gaffe
'slip' is the definition.
(both can mean an error or blunder)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gaffe that I've seen before include "Brick (that's dropped)" , "embarrassing mistake" , "indiscreet remark" , "embarrassing error" , "Boob" .)
