Literal dash following motorway (8)
I believe the answer is:
misprint
'literal' is the definition.
(I know that literal can be written as misprint)
'dash following motorway' is the wordplay.
'dash' becomes 'sprint' (synonyms).
'following' means one lot of letters go next to another.
'motorway' becomes 'MI' (resembles Ms, English motorway).
'sprint' put after 'mi' is 'MISPRINT'.
(Other definitions for misprint that I've seen before include "mistake" , "Typo" , "Typing error" , "Type of slip" , "Typical accident" .)
