Thought person in prison camp needs helping (13)
I believe the answer is:
consideration
'thought' is the definition.
(I know that consideration is a type of thought)
'person in prison camp needs helping' is the wordplay.
'person in prison' becomes 'con' (I am not sure about this - if you are sure you should believe this answer much more).
'camp' becomes 'side' (both can mean a group or faction).
'needs' means one lot of letters go next to another.
'helping' becomes 'ration' (a ration is a serving or helping).
'con'+'side'+'ration'='CONSIDERATION'
Can you help me to learn more?
(Other definitions for consideration that I've seen before include "Kindness" , "Study" , "Reward; careful thought" , "factor to be borne in mind" , "Thoughtfulness - relevant factor" .)
