Average, like Scrooge? (4)
I believe the answer is:
mean
I believe this is a double definition.
'average' is the first definition.
(type of average)
'like scrooge?' is the second definition.
(I've seen this in another clue)
(Other definitions for mean that I've seen before include "mercenary" , "Average or mingy" , "Have in mind to be miserly?" , "Name for being tight-fisted" , "Being near" .)
