Plant shop has alarm at the front (5,5)
I believe the answer is:
panic grass
'plant' is the definition.
The answer is an example.
'shop has alarm at the front' is the wordplay.
I cannot really see how this works, but
'shop' could be 'grass' (both are slang for 'to inform on') and 'grass' is present in the answer.
'alarm' could be 'panic' (alarm can mean panic or worry) and 'panic' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for panic grass that I've seen is " cattle fodder".)
