Briefly I draw no conclusion (2,1,4)
I believe the answer is:
in a word
'briefly' is the definition.
(I've seen this in another clue)
'i draw no conclusion' is the wordplay.
'i draw no' can be anagrammed to 'IN A WORD'.
However, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for in a word that I've seen before include "To summarize" , "To summarise (the shortest way possible!)" , "concise" , "To summarise very briefly" , "summing up" .)
