County threw sorceries out (14)
I believe the answer is:
worcestershire
'county' is the definition.
(English county)
'threw sorceries out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'threw'+'sorceries'='threwsorceries'
'threwsorceries' is an anagram of 'WORCESTERSHIRE'.
(Other definitions for worcestershire that I've seen before include "where triennial choir festival staged?" , "saucy locale?" , "English county" .)
