Too near (6)
I believe the answer is:
beside
I believe this clue is a double definition.
'too' is the first definition.
(thesaurus)
'near' is the second definition.
(I've seen this in another clue)
(Other definitions for beside that I've seen before include "- - the point" , "Very near to" , "Next to - compared with" , "Next door to" , "Adjacent to" .)
