Row with distinction (10)
I believe the answer is:
difference
This clue is a double definition.
'row' is the first definition.
(I've seen this before)
'distinction' is the second definition.
(thesaurus)
'with' acts as a link.
(Other definitions for difference that I've seen before include "Variation" , "row" , "Diversity" , "Discrimination" , "Variance; disagreement" .)
