Like Cora, wild about the man who blew the whistle (4,3)

I believe the answer is:
care for
'like cora wild about the man who blew the whistle' is the definition.
'care for' can be an answer for 'like' (I've seen this in another clue). I'm unsure of the remainder of the definition.
'like cora wild about the man' is the wordplay.
'like' becomes 'ef' (I can't explain this - if you can you should believe this answer much more).
'wild' indicates anagramming the letters.
'about' indicates putting letters inside.
'the man' becomes 'r' (abbreviation for rook, a chess piece or 'man').
'cora' anagrammed gives 'caro'.
'ef' placed into 'caro' is 'carefo'.
'carefo'+'r'='CARE FOR'
Can you help me to learn more?
(Another definition for care for that I've seen is " Look after".)
