Socially relevant, clever and working to oust leader (5,2)
I believe the answer is:
right on
'socially relevant' is the definition.
(I've seen this before)
'clever and working to oust leader' is the wordplay.
'clever' becomes 'righto' (I can't justify this - if you can you should give a lot more credence to this answer).
'and' means one lot of letters go next to another.
'working' becomes 'on' (e.g. a machine is working or on).
'to oust leader' means to remove the first letter (I've seen 'ousting leader of' mean this).
'on' with its initial letter taken away is 'n'.
'righto'+'n'='RIGHT-ON'
Can you help me to learn more?
(Other definitions for right on that I've seen before include "Words of encouragement" , "politically correct?" , "American exclamation of approval" , "Interjection expressing agreement" , "Fashionably liberal" .)
