Tender and quiet with her in shack (8)
I believe the answer is:
shepherd
'tender' is the definition.
(I've seen this before)
'quiet with her in shack' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'with' means one lot of letters go next to another.
'in' indicates putting letters inside.
'shack' becomes 'shed' (I've seen this in another clue).
'p'+'her'='pher'
'pher' inserted within 'shed' is 'SHEPHERD'.
'and' acts as a link.
(Other definitions for shepherd that I've seen before include "Steer" , "See 16" , "Herder of sheep" , "Ovine animal-keeper" , "Clergyman perhaps" .)
