Perhaps not dangerous, or safe in the East End (7)
I believe the answer is:
unarmed
'safe in the east end' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'perhaps not dangerous' is the wordplay.
I cannot really see how this works, but
'not' could be 'un' (prefix meaning 'not') and 'un' is found within the answer.
The remaining letters 'armed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for unarmed that I've seen before include "Like Venus de Milo" , "Defenceless" , "Open" , "Not able to fire" , "with no warlike threat?" .)
