Brave figure: a Latin revolutionary (7)
I believe the answer is:
valiant
'brave' is the definition.
(similar in meaning)
'figure a latin revolutionary' is the wordplay.
'figure' becomes 'v' (I can't justify this - if you can you should give a lot more credence to this answer).
'revolutionary' indicates anagramming the letters.
'latin' anagrammed gives 'liant'.
'v'+'a'+'liant'='VALIANT'
Can you help me to learn more?
(Other definitions for valiant that I've seen before include "Brave in battle" , "Showing courage" , "Latvian (anag.)" , "Stout-hearted" , "Brave - resolute" .)
