An attempt to get out, perhaps (6)
I believe the answer is:
excuse
'out perhaps' is the definition.
'excuse' can be an answer for 'out' (I've seen this before). I am unsure of the 'perhaps' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for excuse that I've seen before include "Plea; let off" , "Defence, justification" , "Forgive - allow to pass - plea" , "Condone or forgive" , "Forgive or overlook an offence" .)
