Many pull item out (8)
I believe the answer is:
multiple
'many' is the definition.
('multiple' can be similar in meaning to 'many')
'pull item out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'pull'+'item'='pullitem'
'pullitem' is an anagram of 'MULTIPLE'.
(Other definitions for multiple that I've seen before include "Lit plume (anag)" , "Manifold; numerous" , "Having many parts or components" , "Numerous and often varied" , "Having several parts" .)
