Wild supporter of Chelsea, say, taking against entertaining article (7)
I believe the answer is:
fanatic
'wild supporter' is the definition.
'fanatic' can be an answer for 'supporter' (fanatic is a kind of supporter). I'm unsure of the 'wild' bit.
'chelsea say taking against entertaining article' is the wordplay.
'chelsea say' becomes 'FC' (short for football club - Chelsea FC is an example).
'taking' means one lot of letters goes inside another.
'against' becomes 'anti' (prefix meaning against).
'entertaining' is an insertion indicator (inviting in, as for dinner).
'article' becomes 'a' (the indefinite article in English).
'anti' placed around 'a' is 'anati'.
'fc' placed around 'anati' is 'FANATIC'.
'of' is the link.
Can you help me to learn more?
(Other definitions for fanatic that I've seen before include "Narrow-minded enthusiast" , "Person filled with excessive zeal for cause" , "One who is excessively zealous" , "Freak" , "Obsessive enthusiast" .)
