Weighed up prisoner team with revolutionary (10)
I believe the answer is:
'weighed up' is the definition.
'considered' can be an answer for 'weighed' ('consider' can be a synonym of 'weigh'). I am not certain of the 'up' bit.
'prisoner team with revolutionary' is the wordplay.
'prisoner' becomes 'con' (abbreviation for 'convict').
'team' becomes 'side' (both can mean a sports team).
'with' says to put letters next to each other.
'revolutionary' becomes 'red' (red can informally mean a communist).
Can you help me to learn more?
(Other definitions for considered that I've seen before include "respected" , "Believed to be" , "Looked at" , "Thought carefully about" , "Deliberated" .)
