Cut short a book's English verbatim translation that's miles out (10)
I believe the answer is:
abbreviate
'miles out' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how one could define the other.
'cut short a book's english verbatim translation' is the wordplay.
'cut short' means to remove the last letter.
'book' becomes 'b' (abbreviation for book).
'english' becomes 'e' (abbreviation).
'translation' indicates anagramming the letters.
'a'+'b'+'e'+'verbatim'='abeverbatim'
'abeverbatim' with its final letter removed is 'abeverbati'.
'abeverbati' with letters rearranged gives 'ABBREVIATE'.
'that's' is the link.
(Other definitions for abbreviate that I've seen before include "Shorten (text)" , "Shorten (a word)" .)
