Raise good argument (4)

Ross

I believe the answer is:

grow

'raise' is the definition.
('grow' can be a synonym of 'raise')

'good argument' is the wordplay.
'good' becomes 'g' (abbreviation).
'argument' becomes 'row' (I've seen this before).
'g'+'row'='GROW'

(Other definitions for grow that I've seen before include "Expand" , "Mature" , "Wax" , "Swell" , "Gain in size" .)

I've seen this clue in The Guardian.
