Brighter ace bails out of chopper with spinning soldiers (8)
I believe the answer is:
cleverer
'brighter ace bails out of' is the definition.
I can't judge whether this defines the answer.
'chopper with spinning soldiers' is the wordplay.
'chopper' becomes 'clever' (I can't explain this - if you can you should believe this answer much more).
'with' is an insertion indicator.
'spinning' says the letters should be written backwards.
'soldiers' becomes 're' (Royal Engineers regiment).
're' in reverse letter order is 'er'.
'clever' placed around 'er' is 'CLEVERER'.
Can you help me to learn more?
(Other definitions for cleverer that I've seen before include "More intelligent" , "More mentally quick" , "Mentally quicker" .)
