Stories about Brideshead, possibly learnt at school (6)
I believe the answer is:
tables
'possibly learnt at school' is the definition.
I can't judge whether this definition defines the answer.
'stories about brideshead' is the wordplay.
'stories' becomes 'tales' ('tale' can be a synonym of 'story').
'about' means one lot of letters goes inside another.
'brideshead' becomes 'b' (head letter of 'brides').
'tales' enclosing 'b' is 'TABLES'.
Can you help me to learn more?
(Other definitions for tables that I've seen before include "Turn these to reverse the situation in your own favour" , "Turn these to gain the advantage" , "Sit at the strange stable" , "Turn these to gain the upper hand" , "Facts and figures arranged in columns" .)
