Start to read publication that includes new version (9)
I believe the answer is:
rendition
'version' is the definition.
(I've seen this in another clue)
'start to read publication that includes new' is the wordplay.
'start to' suggests taking the first letters.
'publication' becomes 'edition' (edition is a kind of publication).
'that includes' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
The initial letter of 'read' is 'r'.
'edition' enclosing 'n' is 'endition'.
'r'+'endition'='RENDITION'
(Other definitions for rendition that I've seen before include "Handing over of prisoners to countries where torture is allowed" , "Account" , "(Musical) performance" , "Interpretation (of e.g. song)" , "Dramatic performance" .)
