Content to lie very quietly in dry grass (5)
I believe the answer is:
happy
'content' is the definition.
(content can mean happy or pleased)
'quietly in dry grass' is the wordplay.
'quietly' becomes 'pp' (musical abbreviation for pianissimo).
'in' is an insertion indicator.
'dry grass' becomes 'hay' (I've seen this in another clue).
'pp' put into 'hay' is 'HAPPY'.
'to lie very' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for happy that I've seen before include "Fortunate; content" , "Delighted" , "One of the Seven Dwarves" , "Carefree" , "Pleased; fortunate" .)
