Leg cane damaged is tender (7)
I believe the answer is:
pinnace
'is tender' is the definition.
(I've seen this before)
'leg cane damaged' is the wordplay.
'leg' becomes 'pin' (pin is a kind of leg**).
'damaged' indicates anagramming the letters.
'cane' with letters rearranged gives 'nace'.
'pin'+'nace'='PINNACE'
(Other definitions for pinnace that I've seen before include "tender" , "Small boat" , "Ship's boat - nice nap (anag)" , "Vessel" .)
