Engineer shut yard for some time (8)
I believe the answer is:
thursday
'some time' is the definition.
'engineer shut yard' is the wordplay.
'engineer' indicates anagramming the letters.
'shut'+'yard'='shutyard'
'shutyard' anagrammed gives 'THURSDAY'.
'for' acts as a link.
(Other definitions for thursday that I've seen before include "Shut yard (anag.)" , "The Man Who Was -- (G.K. Chesterton)" , "twenty-four hours" , "child born then has far to go" , "Chesterton's man" .)
