Curving flight of e.g. fly cut in half - what keeps it up? (7)
I believe the answer is:
inswing
'curving flight of e g fly' is the definition.
I can't tell whether this defines the answer.
'cut in half what keeps it up?' is the wordplay.
I cannot really understand how this works, but
'cut' could be 'swing' (synonyms) and 'swing' is located in the answer.
'in' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for inswing that I've seen is " Movement through the air towards the batsman".)
