Form a liking for version two, we hear (4,2)
I believe the answer is:
take to
'form a liking for' is the definition.
(I've seen this in another clue)
'version two we hear' is the wordplay.
'version' becomes 'take' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'we hear' shows a homophone (sound like).
'two' is a homophone of 'to'.
'take'+'to'='TAKE TO'
Can you help me to learn more?
(Other definitions for take to that I've seen before include "Develop a liking for, or adopt as habit" , "Become fond of" , "Develop a particular liking for" , "Develop liking or ability for" , "Like" .)
