Somehow, growing wheat besieged by butterfly family finally (4,4,3)
I believe the answer is:
come what may
'somehow growing' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'wheat besieged by butterfly family finally' is the wordplay.
I cannot quite see how this works, but
an anagram of 'wheat' is 'ewhat' which is within the answer.
'butterfly' could be 'comma' (comma is a kind of butterfly) and 'comma' is found within the leftover letters.
A single letter 'y' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for come what may that I've seen before include "Regardless" , "No matter what happens" , "Whatever happens" , "In spite of anything that might happen" .)
