Genuine misprint (7)
I believe the answer is:
literal
This clue is a double definition.
'genuine' is the first definition.
(literal can mean genuine or factual)
'misprint' is the second definition.
(printing term for misprinted letter)
(Other definitions for literal that I've seen before include "Accurate and unexaggerated" , "Lacking imagination; misprint" , "A tiller (anag.)" , "Exact (translation)" , "according to specifications" .)
