Flood diverted infield (6)
I believe the answer is:
influx
This clue could be a double definition.
'flood' is the first definition.
(I've seen this before)
'diverted infield' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
Can you help me to learn more?
(Other definitions for influx that I've seen before include "Arrival in large numbers" , "Large-scale arrival" , "Arrival - invasion" , "Inundation" , "Sudden arrival in numbers" .)
