Value to throw out (5)
I believe the answer is:
worth
'value' is the definition.
(I've seen this before)
'throw out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'throw' is an anagram of 'WORTH'.
'to' acts as a link.
(Other definitions for worth that I've seen before include "Merit - value" , "Throw (anag.)" , "Value (of something)" .)
