Fill ward (6)

Ross

I believe the answer is:

charge

This clue is a double definition.

'fill' is the first definition.
(charging is a kind of filling)

'ward' is the second definition.
(thesaurus)

(Other definitions for charge that I've seen before include "Set price or mount onslaught" , "Formally accuse (someone)" , "Amount to pay - attack" , "Attack - cost" , "Rush forward - cost" .)

I've seen this clue in The Independent.
