Much time and trouble is taken in its drafting (6)
I believe the answer is:
agenda
'taken in its drafting' is the definition.
I can't tell whether this defines the answer.
'much time and trouble' is the wordplay.
'much' means to remove the last letter (much but not all of the word).
'time' becomes 'ages' (ages can informally mean a long period).
'trouble' indicates an anagram.
'ages' with its final letter taken off is 'age'.
'and' is an anagram of 'nda'.
'age'+'nda'='AGENDA'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for agenda that I've seen before include "To-do list" , "Timetable" , "Meet to discuss this" , "Schedule of items for meeting" , "plan of things to be done" .)
