Writer's mistakes in Latin (6)
I believe the answer is:
errata
'writer's mistakes' is the definition.
'errata' can be an answer for 'mistakes' (an erratum is a mistake in a printed work). I am not certain of the 'writer's' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for errata that I've seen before include "List of text corrections to be made in a publication" , "corrected mistakes" , "Mistakes (Latin)" , "(Printing) errors" , "Mistakes in printing or writing" .)
