The Wire ... so extraordinary and different (9)
I believe the answer is:
otherwise
'different' is the definition.
(thesaurus)
'the wire so extraordinary' is the wordplay.
'extraordinary' is an anagram indicator.
'the'+'wire'+'so'='thewireso'
'thewireso' is an anagram of 'OTHERWISE'.
'and' is the link.
(Other definitions for otherwise that I've seen before include "White rose (anag.)" , "Apart from that" , "White rose seen in a different way" , "As an alternative - like white rose" , "In other respects or ways" .)
