Undesirable cryptic clue women (9)
I believe the answer is:
unwelcome
'undesirable' is the definition.
(thesaurus)
'cryptic clue women' is the wordplay.
'cryptic' indicates an anagram (a cryptic or obscure order of the letters).
'clue'+'women'='cluewomen'
'cluewomen' with letters rearranged gives 'UNWELCOME'.
(Other definitions for unwelcome that I've seen before include "Not gladly received" , "Causing displeasure" , "Not wanted" , "Not greeted or received with pleasure, quite the opposite" , "Bad (news); not acceptable" .)
