Don't leave any more in this dire shambles (10)
I believe the answer is:
disinherit
'don't leave any more' is the definition.
I can't judge whether this definition defines the answer.
'in this dire shambles' is the wordplay.
'shambles' is an anagram indicator.
'in'+'this'+'dire'='inthisdire'
'inthisdire' with letters rearranged gives 'DISINHERIT'.
Can you help me to learn more?
(Other definitions for disinherit that I've seen before include "Remove as heir" , "Write out of a will" , "Lanarkshire town" , "Cut off as with a shilling" .)
