Freedom from disturbance on street (4)
I believe the answer is:
rest
'freedom from disturbance' is the definition.
'rest' can be an answer for 'freedom' (thesaurus). I am unsure of the 'from disturbance' bit.
'on street' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'street' becomes 'st' (abbreviation).
're'+'st'='REST'
Can you help me to learn more?
(Other definitions for rest that I've seen before include "'''God ... ye, merry gentlemen'' (carol) (4)'" , "Holiday" , "Lie down" , "Balance" , "Settle" .)
