Average, like Scrooge? (4)
I believe the answer is:
mean
I believe this clue is a double definition.
'average' is the first definition.
(type of average)
'like scrooge?' is the second definition.
(Dickens' Ebenezer Scrooge is mean or miserly)
(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" .)
