Half of Split (3,2,3)
I believe the answer is:
cut in two
'half of split' is the definition.
'cut in two' can be an answer for 'split' (thesaurus). I am unsure of the 'half of' bit.
'split' is the wordplay.
I cannot quite understand how this works, but
'split' could be 'intwo' (I've seen this in another clue) and 'intwo' is present in the answer.
The remaining letters 'cut' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cut in two that I've seen before include "Divide in halves with knife" , "Separate" .)
