Average guy (4)
I believe the answer is:
norm
This clue could be a double definition.
'average' is the first definition.
('norm' can be a synonym of 'average')
'guy' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
Can you help me to learn more?
(Other definitions for norm that I've seen before include "Drawing stick" , "Something typical" , "Average level of achievement" , "Typical pattern or situation" , "Standard considered to be representative" .)
