For the broken leg, will get a doctor in, you bet (6)
I believe the answer is:
gamble
'you bet' is the definition.
'gamble' can be an answer for 'bet' (I've seen this before). I am not sure about the 'you' bit.
'for the broken leg will get a doctor' is the wordplay.
'for' becomes 'mb' (I can't explain this - if you can you should believe this answer much more).
'the broken' means one lot of letters goes inside another (inserted letters break into others).
'will get' says to put letters next to each other.
'doctor' is an anagram indicator.
'leg'+'a'='lega'
'lega' is an anagram of 'gale'.
'mb' inserted into 'gale' is 'GAMBLE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for gamble that I've seen before include "Take a risk" , "Place bets" , "punt" , "Take risks" , "Take a chance, speculate" .)
