Possibly tore in from the East (6)
I believe the answer is:
orient
'the east' is the definition.
(synonyms)
'possibly tore in' is the wordplay.
'possibly' indicates an anagram.
'tore'+'in'='torein'
'torein' with letters rearranged gives 'ORIENT'.
'from' is the link.
(Other definitions for orient that I've seen before include "Asia" , "Align (relative to a specific direction)" , "Determine position with regard to points of compass" , "Famous express" , "Acquaint with position" .)
