Misprint in literature on period of history ending in turmoil (7)
I believe the answer is:
literal
'misprint' is the definition.
('literal' can be a synonym of 'misprint')
'literature on period of history ending in turmoil' is the wordplay.
'literature' becomes 'lit'.
'on' is a charade indicator (letters next to each other).
'period of history' becomes 'era' (I've seen this before).
'ending in' indicates one should take the final letters.
The last letter of 'turmoil' is 'l'.
'lit'+'era'+'l'='LITERAL'
'in' acts as a link.
(Other definitions for literal that I've seen before include "Textual error" , "Precise" , "All tire (anag.)" , "Simple" , "Not figurative" .)
