Go and live in a refuge (4,1,7)
I believe the answer is:
beat a retreat
'go' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'live in a refuge' is the wordplay.
I cannot quite see how this works, but
'live' could be 'are' ('they live' means 'they are') and 'are' is found within the answer.
'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for beat a retreat that I've seen before include "Go away in a hurry" , "Withdraw quickly" , "Withdraw to avoid something unpleasant" , "Retire hastily" , "Depart hastily" .)
