Different kinds of neckwear for one to rave wildly about (9)
I believe the answer is:
varieties
'different kinds' is the definition.
'varieties' can be an answer for 'kinds' (variety is a kind of kind). I am not certain of the 'different' bit.
'neckwear for one to rave wildly about' is the wordplay.
'neckwear' becomes 'ties' (I've seen this in another clue).
'for' says to put letters next to each other (I've seen this in other clues).
'one to' becomes 'i' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'wildly' indicates an anagram.
'about' means one lot of letters goes inside another.
'rave' is an anagram of 'vare'.
'i' inserted into 'vare' is 'varie'.
'ties' after 'varie' is 'VARIETIES'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for varieties that I've seen before include "Types" , "All sorts" , "classes" , "one used to find in a palace?" , "Assortments,diversities" .)
