Shocking rates clan inherited (9)
I believe the answer is:
ancestral
'inherited' is the definition.
(I've seen this before)
'shocking rates clan' is the wordplay.
'shocking' indicates anagramming the letters (letters shocked or shaken).
'rates'+'clan'='ratesclan'
'ratesclan' is an anagram of 'ANCESTRAL'.
(Other definitions for ancestral that I've seen before include "Coming down the tree" , "description of voices prophesying war?" , "handed down by family" , "Belonging to the house" , "from old-timers" .)
