Drunken wag outside hostelry under shade (6)
I believe the answer is:
awning
'shade' is the definition.
(thesaurus)
'drunken wag outside hostelry under' is the wordplay.
'drunken' is an anagram indicator.
'outside' indicates putting letters inside.
'hostelry under' becomes 'nin' (I can't explain this - if you can you should give a lot more credence to this answer).
'wag' with letters rearranged gives 'awg'.
'awg' enclosing 'nin' is 'AWNING'.
Can you help me to learn more?
(Other definitions for awning that I've seen before include "Canvas sunshield" , "Protective cover" , "Canvas covering in front of shop" , "Canvas frame stretched as shelter against sun or rain" , "Canopy of canvas for shelter" .)
