See a street in depression (6)
I believe the answer is:
valley
'depression' is the definition.
(valley is a kind of depression)
'see a street' is the wordplay.
'see' becomes 'v' (Latin 'vide', used to direct a reader to a source).
'a street' becomes 'alley' (type of small or narrow street).
'v'+'alley'='VALLEY'
'in' is the link.
(Other definitions for valley that I've seen before include "Dale, dene or glen" , "See 14" , "den" , "Flat area of land flanked by hills" , "in victory with large marble" .)
