I'm a little stuck... Click here to teach me more about this clue!

'genuine' is the definition.
(literal can mean genuine or factual)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for literal that I've seen before include "Lacking imagination; misprint" , "A tiller (anag.)" , "Accurate and unexaggerated" , "Exact (translation)" , "Unimaginative" .)

I've seen this clue in The Times.
