One day in tabloid elevated male page 3 behaviour? (6)
I believe the answer is:
nudism
'page 3 behaviour?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'one day in tabloid elevated male' is the wordplay.
'one day' becomes 'id' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'tabloid' becomes 'Sun' (The Sun, UK newspaper).
'elevated' is a reversal indicator (in a down clue, letters go up).
'male' becomes 'm' (common abbreviation).
'id' placed into 'sun' is 'sidun'.
'sidun' written backwards gives 'nudis'.
'nudis'+'m'='NUDISM'
Can you help me to learn more?
(Other definitions for nudism that I've seen before include "taking off habitually" , "Going without clothes, socially" , "Mind us (anag)" , "Pursuit of a naturist" , "Having nothing on" .)
