I'll tear off, to be exact (7)
I believe the answer is:
literal
'be exact' is the definition.
('literal' can be similar in meaning to 'exact')
'i'll tear off' is the wordplay.
'off' is an anagram indicator.
'ill'+'tear'='illtear'
'illtear' with letters rearranged gives 'LITERAL'.
'to' is the link.
(Other definitions for literal that I've seen before include "Unimaginative" , "A tiller (anag.)" , "Following the exact meaning" , "Taking words in their most basic sense" , "Verbatim - true" .)
