Hail in the street (3)

I believe the answer is:

ave

I believe this clue is a double definition.

'hail' is the first definition.
(greeting in Latin)

'street' is the second definition.
(short for avenue)

'in the' acts as a link.

(Other definitions for ave that I've seen before include "Hail in old Rome" , "Hail to the old Romans" , "Hail as to Maria" , "Roman greeting" , "Hail as to Caesar" .)

I've seen this clue in the Evening Standard.
