Cryptic clues he'd put in list (8)
I believe the answer is:
schedule
'list' is the definition.
(I know that schedule is a type of list)
'cryptic clues he'd put in' is the wordplay.
'cryptic' is an anagram indicator (a cryptic or obscure order of the letters).
'put in' indicates putting letters inside.
'clues' anagrammed gives 'scule'.
'scule' placed around 'hed' is 'SCHEDULE'.
(Other definitions for schedule that I've seen before include "Syllabus" , "Rota" , "List of duties, etc" , "Timetable; plan of action" , "Timetable of planned events or work" .)
