Dined in shed: empty or full? (5)
I believe the answer is:
sated
'full?' is the definition.
(I've seen this in another clue)
'dined in shed empty' is the wordplay.
'dined' becomes 'ate' (I've seen this in another clue).
'in' means one lot of letters goes inside another.
'empty' means to remove the middle letters.
'shed' with its centre taken out is 'sd'.
'ate' inserted inside 'sd' is 'SATED'.
'or' is the link.
(Other definitions for sated that I've seen before include "fully filled" , "Stuffed with food, too full" , "Replete" , "completely filled?" , "Filled to satisfaction" .)
