Submit dossier (4)
I believe the answer is:
file
I believe this is a double definition.
'submit' is the first definition.
(thesaurus)
'dossier' is the second definition.
(a dossier is a file or set of information)
(Other definitions for file that I've seen before include "Smoothing tool; organised data" , "Dosssier" , "Folder; rasp" , "Tool for sawing through metal" , "Set of papers" .)
