How one might describe letters briefly (2,1,4)
I believe the answer is:
in a word
'briefly' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for in a word that I've seen before include "Where a number of characters may be found" , "To summarise (the shortest way possible!)" , "Briefly - won raid (anag)" , "To summarize" , "To sum up" .)
