Hail lovely ground (6)
I believe the answer is:
Here is my best explanation:
'hail' is the definition.
'lovely ground' is the wordplay.
'ground' indicates an anagram (grind the letters ).
'lovely' is an anagram of 'VOLLEY'.
(Other definitions for volley that I've seen before include "Shot played before the ball bounces", "A flight of missiles", "Lovely (anag.)", "Simultaneous discharge of a number of firearms", "Lovely kind of tennis stroke", "Simultaneous shooting of a number of weapons", "Cannonade", "Tennis stroke", "Tennis, football, shot" and "Salvo (of bullets)".)
