See sign is incorrect, for a start (7)
I believe the answer is:
genesis
'a start' is the definition.
(thesaurus)
'see sign is incorrect' is the wordplay.
'is incorrect' is an anagram indicator.
'see'+'sign'='seesign'
'seesign' with letters rearranged gives 'GENESIS'.
'for' is the link.
(Other definitions for genesis that I've seen before include "Old Testament Book 1" , "Band; book" , "religious book?" , "Creation" , "rock band" .)
