Intend to be penny-pinching on average (4)
I believe the answer is:
mean
This clue is a triple definition!
'intend' is the first definition.
(I know that intend can be written as mean)
'to be penny-pinching' is the second definition.
(I've seen this in another clue)
'on' acts as a link.
'average' is the third definition.
(type of average)
(Other definitions for mean that I've seen before include "Scrooge?" , "Name for being tight-fisted" , "Close" , "Intend - miserly" , "Represent - average" .)
