I'll get into it, prepared to fly (4)
I believe the answer is:
wing
'to fly' is the definition.
(synonyms)
'i'll get into it prepared' is the wordplay.
I cannot really understand how this works, but
'get' could be 'win' (winning is a kind of getting) and 'win' is present in the answer.
A single letter 'g' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for wing that I've seen before include "Take . . . . to fly like a bird" , "Footballer" , "Aircraft's support" , "Side piece" , "Organ of flight" .)
