Give line out showing lure (8)
I believe the answer is:
inveigle
'lure' is the definition.
(thesaurus)
'give line out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'give'+'line'='giveline'
'giveline' anagrammed gives 'INVEIGLE'.
'showing' acts as a link.
(Other definitions for inveigle that I've seen before include "use enticements" , "Wheedle" , "Lead on, entice" , "Persuade by trickery - given lie (anag)" , "Persuade by flattery" .)
