Increase offer (3,2)
I believe the answer is:
put up
I believe this is a double definition.
'increase' is the first definition.
(thesaurus)
'offer' is the second definition.
(thesaurus)
(Other definitions for put up that I've seen before include "unfair sort of job" , "Not such a fair job" , "Provide a bed for the night" , "Accommodated" , "Take lodgings" .)
