Showing tiredness, perhaps, leaving yard for shade (6)
I believe the answer is:
awning
'shade' is the definition.
(thesaurus)
'showing tiredness perhaps leaving yard' is the wordplay.
'showing tiredness perhaps' becomes 'yawning'.
'leaving' is a deletion indicator.
'yard' becomes 'y'.
'yawning' with 'y' taken out is 'AWNING'.
'for' acts as a link.
(Other definitions for awning that I've seen before include "Roof-like canvas shelter over a doorway" , "Canvas shade" , "Sunshade" , "Covering above a window or door" , "Canvas cover over a shop entrance" .)
