Delight in quiet meadow by state borders (6)
I believe the answer is:
please
'delight' is the definition.
(I know that delight can be written as please)
'quiet meadow by state borders' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'meadow' becomes 'lea' (a lea is a grassy area).
'by' means one lot of letters go next to another.
'borders' suggests removing the centre (only the edge or border letters remain).
'state' with its middle taken out is 'se'.
'p'+'lea'+'se'='PLEASE'
'in' is the link.
(Other definitions for please that I've seen before include "If you'd be so kind?" , "Polite word of request" , "Make happy or glad" , "Beatles song (request to oblige?)" , "Entertain" .)
