Follows a possible fall of the pound? (5)
I believe the answer is:
tails
'follows a possible fall' is the definition.
'tails' can be an answer for 'follows' (I've seen this in another clue). I'm unsure of the 'a possible fall' bit.
'the pound?' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'pound?' becomes 'ails' (I can't explain this - if you can you should believe this answer much more).
't'+'ails'='TAILS'
'of' is the link.
Can you help me to learn more?
(Other definitions for tails that I've seen before include "Follows closely" , "Gambler's choice" , "as opposed to heads" , "Ends" , "the back of bears - bulls too" .)
