Normal idea strange for secret diarist (6,4)
I believe the answer is:
adrian mole
'secret diarist' is the definition.
'adrian mole' can be an answer for 'diarist' (I've seen this before). I am not certain of the 'secret' bit.
'normal idea strange' is the wordplay.
'strange' indicates an anagram.
'normal'+'idea'='normalidea'
'normalidea' with letters rearranged gives 'ADRIAN MOLE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for adrian mole that I've seen before include "Fictional teenage diary-keeper" , "diarist" , "Young journalist" .)
