Thought Conservative team communist? (10)
I believe the answer is:
considered
'thought' is the definition.
(considering is a kind of thinking)
'conservative team communist?' is the wordplay.
'conservative' becomes 'con' (I've seen this in other clues).
'team' becomes 'side' (I've seen this before).
'communist?' becomes 'red' (red is a kind of communist).
'con'+'side'+'red'='CONSIDERED'
(Other definitions for considered that I've seen before include "Deliberated" , "respected" , "Thought carefully about" , "Looked at" , "Believed to be" .)
