A pot I smashed in courtyard (5)
I believe the answer is:
patio
'courtyard' is the definition.
(I've seen this before)
'a pot i smashed' is the wordplay.
'smashed' indicates an anagram.
'a'+'pot'+'i'='apoti'
'apoti' is an anagram of 'PATIO'.
'in' acts as a link.
(Other definitions for patio that I've seen before include "Where Barbie might be held" , "Paved area outside house" , "Inner courtyard" , "Hard surface" , "Exterior paved area" .)
