Crossword Genius

Lower payment? (3)

Ross

I believe the answer is:

sub

I believe this is a double definition.

'lower' is the first definition.
(thesaurus)

'payment?' is the second definition.
(I have seen 'Advance payment ' mean 'sub' so perhaps 'payment' could also mean 'sub')

(Other definitions for sub that I've seen before include "Underwater craft" , "Underwater boat" , "Prefix meaning beneath" , "Junior editor" , "Prefix denoting under" .)

I've seen this clue in the Evening Standard.
