Stand up and leer around British revolutionary (5)
I believe the answer is:
rebel
'stand up' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how one could define the other.
'leer around british revolutionary' is the wordplay.
'around' is an insertion indicator.
'british' becomes 'b' (abbreviation e.g. in BBC).
'revolutionary' says the letters should be written in reverse (letters revolve around).
'leer' placed around 'b' is 'leber'.
'leber' in reverse letter order is 'REBEL'.
'and' is the link.
Can you help me to learn more?
(Other definitions for rebel that I've seen before include "Oppose authority" , "revolutionary" , "Revolting person" , "Do things differently" , "Rise up against authority" .)
