Raised in Scots-English breeding ground (4)
I believe the answer is:
nest
'breeding ground' is the definition.
(I've seen this in other clues)
'raised in scots-english' is the wordplay.
'raised' shows that the letters should be reversed in order.
'in' indicates a hidden word.
'tsen' can be found hidden inside 'scots english'.
'tsen' reversed gives 'NEST'.
(Other definitions for nest that I've seen before include "Place of retreat" , "Eyrie" , "Rook's residence?" , "Cosy retreat" , "comfortable residence" .)
