No one for turning out in the morning (8)
I believe the answer is:
forenoon
'the morning' is the definition.
(synonyms)
'no one for turning out' is the wordplay.
'turning out' indicates anagramming the letters.
'no'+'one'+'for'='noonefor'
'noonefor' is an anagram of 'FORENOON'.
'in' is the link.
(Other definitions for forenoon that I've seen before include "Morning (nautical)" , "in the morning - with 19d" , "twelve o'clock" .)
