As a whole, all together (2,4)
I believe the answer is:
en bloc
I believe this is a double definition.
'as a whole' is the first definition.
(thesaurus)
'all together' is the second definition.
(I've seen this before)
(Other definitions for en bloc that I've seen before include "All together (French)" , "As a whole (body)" , "As a group (Fr.)" , "All together, en masse" , "All together - as a whole" .)
