Passed information about a figure (5)
I believe the answer is:
given
'a figure' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'passed information about' is the wordplay.
'passed' becomes 'iv' (I can't justify this - if you can you should believe this answer much more).
'information' becomes 'gen' (gen can informally mean information).
'about' means one lot of letters goes inside another.
'iv' put inside 'gen' is 'GIVEN'.
Can you help me to learn more?
(Other definitions for given that I've seen before include "assumed fact" , "Provided" , "Donated" , "Taken as read" , "Known fact" .)
