Feature in how to turn a cat into a man (6)
I believe the answer is:
detail
'feature in' is the definition.
'detail' can be an answer for 'feature' (I've seen this in another clue). I'm unsure of the 'in' bit.
'to turn a cat into a man' is the wordplay.
'to turn a cat' becomes 'tai' (I can't justify this - if you can you should give a lot more credence to this answer).
'into' means one lot of letters goes inside another.
'a man' becomes 'Del'.
'tai' going within 'del' is 'DETAIL'.
'how' acts as a link.
Can you help me to learn more?
(Other definitions for detail that I've seen before include "Tailed into particulars" , "A small or subordinate particular" , "Tailed into minutiae" , "Factor" , "Give full info about" .)
