Talks wildly about odd men as 'residue' (8)
I believe the answer is:
remnants
'as residue' is the definition.
I can't tell whether this definition defines the answer.
'talks wildly about odd men' is the wordplay.
'talks wildly' becomes 'rants' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'odd' indicates an anagram.
'men' with letters rearranged gives 'emn'.
'rants' placed around 'emn' is 'REMNANTS'.
Can you help me to learn more?
(Other definitions for remnants that I've seen before include "hangovers" , "Stern man has left-over pieces" , "Pieces of fabric left over" , "Leftovers, scraps" , "Remains" .)
