Way shown by second elder, say, with time (6)
I believe the answer is:
street
'way' is the definition.
(street is a kind of way)
'second elder say with time' is the wordplay.
'second' becomes 's' (common abbreviation).
'elder say' becomes 'tree' (elder is a kind of tree).
'with' means one lot of letters go next to another.
'time' becomes 't'.
's'+'tree'+'t'='STREET'
'shown by' is the link.
(Other definitions for street that I've seen before include "Town road" , "Perry's Della" , "Tester (anag.)" , "Town thoroughfare" , "Urban road" .)
