Pay attention to place across street - it's new (6)
I believe the answer is:
listen
'pay attention to' is the definition.
(thesaurus)
'place across street it's new' is the wordplay.
'place' becomes 'lie' (lie is a kind of place**).
'across' indicates putting letters inside.
'street' becomes 'st'.
'it's new' becomes 'n'.
'lie' going around 'st' is 'liste'.
'liste'+'n'='LISTEN'
(Other definitions for listen that I've seen before include "Hark!" , "Harken" , "Be silent in order to hear" , "Attend (to a sound)" , "Give ear (to)" .)
