New word in some lingo - weird (9)
I believe the answer is:
neologism
'new word' is the definition.
(thesaurus)
'some lingo weird' is the wordplay.
'weird' indicates an anagram.
'some'+'lingo'='somelingo'
'somelingo' with letters rearranged gives 'NEOLOGISM'.
'in' is the link.
(Other definitions for neologism that I've seen before include "new term" , "coinage" , "Newly-coined word or expression" , "Newly coined word" , "New word or phrase" .)
