So go away (5)
I believe the answer is:
hence
This could be a double definition.
'so' is the first definition.
(thesaurus)
'away' is the second definition.
(thesaurus)
'go' is the link.
This may not be right. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for hence that I've seen before include "As a consequence" , "From this time, or for this reason" , "As a result" , "For this reason; in the future" , "In the future; begone!" .)
