Average -- or low? (4)
I believe the answer is:
mean
I believe this is a double definition.
'average' is the first definition.
(type of average)
'low?' is the second definition.
(thesaurus)
'or' is the link.
(Other definitions for mean that I've seen before include "Intend - miserly" , "Name for being tight-fisted" , "Bad-tempered" , "Stingy; Scrooge-like" , "Signify; tight" .)
