In the past, you would have bandaged correct digit (5)
I believe the answer is:
three
'bandaged correct digit' is the definition.
'three' can be an answer for 'digit' (three is a kind of digit). I'm unsure of the 'bandaged correct' bit.
'in the past you' is the wordplay.
'in' indicates putting letters inside.
'past you' becomes 're' (I can't explain this - if you can you should believe this answer much more).
'the' enclosing 're' is 'THREE'.
'would have' is the link.
Can you help me to learn more?
(Other definitions for three that I've seen before include "III" , "Subject of 1 9" , "Number of Furies or Norns" , "Number of feet in a yard" , "Trinity, triad" .)
