Pirate's prop to fix on stage? (3,3)
I believe the answer is:
peg leg
'pirate's prop' is the definition.
(pirates are often shown with wooden legs)
'fix on stage?' is the wordplay.
'fix' becomes 'peg' (to fix or attach with a peg).
'on' means one lot of letters go next to another.
'stage?' becomes 'leg' (a leg is a stage of a competition).
'peg'+'leg'='PEG-LEG'
'to' is the link.
(Other definitions for peg leg that I've seen before include "Person with a wooden limb" , "Informally, an artificial lower limb" , "Artificial limb (usually of wood)" , "Silver piece's replacement" , "(Person with) artificial limb" .)
