Sad sheriffs suggest releasing Western (10)
I believe the answer is:
lamentable
'sad' is the definition.
(I know that sad can be written as lamentable)
'sheriffs suggest releasing western' is the wordplay.
'sheriffs' becomes 'lawmen' (lawman can mean a US sheriff).
'suggest' becomes 'table' (as in tabling a motion).
'releasing' suggests deleting specific letters.
'western' becomes 'w'.
'lawmen'+'table'='lawmentable'
'lawmentable' with 'w' taken away is 'LAMENTABLE'.
(Other definitions for lamentable that I've seen before include "Pitiful" , "Deplorable, regrettable" , "Awful" , "Sorry" .)
