The usual hailstorm (7)
I believe the answer is:
average
This could be a double definition.
'the usual' is the first definition.
(I've seen this before)
'hailstorm' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for average that I've seen before include "Mean - ordinary" , "just like any other" , "Fair to middling" , "About normal or usual" , "mean maybe" .)
