Something soothing spoken in royal residence (8)
I believe the answer is:
balmoral
'royal residence' is the definition.
(I've seen this before)
'something soothing spoken' is the wordplay.
'something soothing' becomes 'balm' (I've seen this before).
'spoken' becomes 'oral' ('oral' can be similar in meaning to 'spoken').
'balm'+'oral'='BALMORAL'
'in' is the link.
(Other definitions for balmoral that I've seen before include "Royal place" , "Royal castle in Scotland" , "Scottish holiday residence of British royals" , "Royal residence - walking shoe - Scottish military hat" , "British royal summer residence" .)
