Glorious under the Linden tree? (7)
I believe the answer is:
sublime
'glorious' is the definition.
('sublime' can be similar in meaning to 'glorious')
'under the linden tree?' is the wordplay.
'under' becomes 'sub' (I've seen this before).
'the linden tree?' becomes 'lime' ('lime' can be a synonym of 'linden tree').
'sub'+'lime'='SUBLIME'
(Other definitions for sublime that I've seen before include "Heavenly" , "Magnificent" , "Exalted; awesome" , "Unparalleled, extreme" , "Wonderful" .)
