It's daft, it's obvious that it's crazy, initially (7)
I believe the answer is:
'it's daft it's obvious that it's crazy initially' is the definition.
'idiotic' can be an answer for 'it's daft' (I've seen this before). I am not sure about the remainder of the definition.
'it's daft it's obvious that it's crazy initially' is the wordplay.
'initially' suggests taking the first letters.
The initial letters of 'its daft its obvious that its crazy' is 'IDIOTIC'.
Can you help me to learn more?
(Other definitions for idiotic that I've seen before include "Mindless" , "Altogether nonsensical" , "Silly" , "Ridiculous" , "without any point" .)
