Tedious list (6)
I believe the answer is:
litany
'tedious list' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for litany that I've seen before include "Tedious series (of complaints)" , "Long list (of requests or complaints)" , "Ceremonial form of prayer" , "Long list - prayer" , "Repetitive series" .)
