Cut off in this dire resort (10)
I believe the answer is:
disinherit
'cut off' is the definition.
(thesaurus)
'in this dire resort' is the wordplay.
'resort' is an anagram indicator.
'in'+'this'+'dire'='inthisdire'
'inthisdire' with letters rearranged gives 'DISINHERIT'.
(Other definitions for disinherit that I've seen before include "Lanarkshire town" , "Cut off as with a shilling" , "Remove as heir" , "Write out of a will" .)
