In an emergency situation, steal (5)
I believe the answer is:
pinch
This clue could be a double definition.
'in an emergency' is the first definition.
'pinch' can be an answer for 'emergency' (synonyms). I am unsure of the 'in an' bit.
'situation steal' is the second definition.
'pinch' can be an answer for 'steal' (pinch can mean to steal). I'm not certain of the 'situation' bit.
Can you help me to learn more?
(Other definitions for pinch that I've seen before include "Grip tightly; steal (colloq.)" , "Squeeze painfully" , "Steal (colloq.); one felt by the poor" , "appropriate" , "Pilfer" .)
