Settles on a silent version (7)
I believe the answer is:
entails
'settles' is the definition.
Although both the answer and definition are verbs in their -s form, I can't see how one could define the other.
'on a silent version' is the wordplay.
'on' is an insertion indicator (as in clothing \'on\' a person).
'version' is an anagram indicator.
'silent' is an anagram of 'entils'.
'a' placed within 'entils' is 'ENTAILS'.
Can you help me to learn more?
(Other definitions for entails that I've seen before include "Has as a direct consequence" , "Has as a logical consequence" , "Necessitates" , "limits of will" , "Involves, makes necessary" .)
