Dislike missing a translation (7)
I believe the answer is:
version
'translation' is the definition.
('version' can be a synonym of 'translation')
'dislike missing a' is the wordplay.
'dislike' becomes 'aversion' (aversion is a kind of dislike).
'missing' suggests deleting specific letters.
'aversion' with 'a' taken out is 'VERSION'.
(Other definitions for version that I've seen before include "Particular form (of something)" , "Particular account of a matter" , "See 24" , "Adaptation" , "Account from one point of view" .)
