Give line out to reveal lure (8)
I believe the answer is:
inveigle
'lure' is the definition.
(thesaurus)
'give line out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'give'+'line'='giveline'
'giveline' with letters rearranged gives 'INVEIGLE'.
'to reveal' acts as a link.
(Other definitions for inveigle that I've seen before include "Persuade by trickery - given lie (anag)" , "Coax, sweet-talk" , "Seduce" , "use enticements" , "Persuade by cajolery" .)
