On the subject of (5)

Ross

I believe the answer is:

about

'on the subject of' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for about that I've seen before include "'All - - Eve' (film)" , "not far away" , "in action" , "Concerning; approximately" , "Concerning; roughly" .)

I've seen this clue in The Times, the Universal and The Irish Times.
