Thought it wrong to take time out (6)
I believe the answer is:
notion
'thought' is the definition.
(notion is a kind of thought)
'it wrong to take time out' is the wordplay.
'wrong' indicates an anagram.
'to take time' becomes 'noon' (I am not sure about this - if you are sure you should believe this answer much more).
'out' is an insertion indicator.
'it' is an anagram of 'ti'.
'ti' going into 'noon' is 'NOTION'.
Can you help me to learn more?
(Other definitions for notion that I've seen before include "clue" , "Vague or whimsical idea" , "Vague understanding" , "Concept, belief" , "desire" .)
