Tired and smashed (9)
I believe the answer is:
shattered
I believe this clue is a double definition.
'tired' is the first definition.
(I've seen this before)
'smashed' is the second definition.
('shattered' can be a synonym of 'smashed')
'and' acts as a link.
(Other definitions for shattered that I've seen before include "after 13 [BREAKING UP]?" , "devastated" , "Completely broken" , "Broken into many pieces" , "Extremely upset" .)
