Row is over woman (5)
I believe the answer is:
issue
'row' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'is over woman' is the wordplay.
'over' means one lot of letters go next to another (in a down clue, some letters go over others).
'woman' becomes 'sue' (woman's name).
'is'+'sue'='ISSUE'
Can you help me to learn more?
(Other definitions for issue that I've seen before include "Emanate" , "Come forth or bring out" , "One's offspring" , "litter" , "Put out; result" .)
