Quickest to cause endless strife? (5)
I believe the answer is:
first
This clue might be a double definition.
'quickest' is the first definition.
Both the definition and answer are adverbs. Maybe they are linked in a way I don't understand?
'endless strife?' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'to cause' acts as a link.
Can you help me to learn more?
(Other definitions for first that I've seen before include "Preliminary" , "Original" , "Position for gold" , "Leading" , "& 2 Early new year arrivals bringing good luck" .)
