One involved in distribution of credits on courses (10)
I believe the answer is:
directions
'courses' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'one involved in distribution of credits on' is the wordplay.
'one' becomes 'i' (Roman numeral).
'involved in' means one lot of letters goes inside another.
'distribution of' indicates an anagram.
'credits'+'on'='creditson'
'creditson' with letters rearranged gives 'directons'.
'i' placed within 'directons' is 'DIRECTIONS'.
Can you help me to learn more?
(Other definitions for directions that I've seen before include "North, south, east and west?" , "News reveals four" .)
