Discontinued, with "out" (6)
I believe the answer is:
phased
'discontinued with out' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for phased that I've seen before include "Done in stages, shaped accordingly" , "Arranged in stages" , "Shaped (anag.)" , "Introduced in stages" , "spread over stages" .)
