Doing nothing in Northwest yet (2,2,3)
I believe the answer is:
up to now
'yet' is the definition.
(thesaurus)
'doing nothing in northwest' is the wordplay.
'doing' becomes 'upto' (as in 'what are you up to?').
'nothing' becomes 'o' (looks like zero - 0).
'in' indicates putting letters inside.
'northwest' becomes 'nw' ('NW' can be a synonym of 'northwest').
'o' inserted inside 'nw' is 'now'.
'upto'+'now'='UP TO NOW'
(Other definitions for up to now that I've seen before include "So far" , "Hitherto" .)
