Mean, medium (7)
I believe the answer is:
average
I believe this is a double definition.
'mean' is the first definition.
(synonyms)
'medium' is the second definition.
(synonyms)
(Other definitions for average that I've seen before include "Mean - typical" , "Arithmetical mean" , "representative figure?" , "just like any other" , "Of no exceptional quality or ability" .)
