Is such diving a bit risky? (3)
I believe the answer is:
sky
'is such diving a bit' is the definition.
I can't tell whether this defines the answer.
'risky?' is the wordplay.
'SKY' is hidden within the letters.
But, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for sky that I've seen before include "Orbiting space-station" , "Strike up" , "-- Blue" , "Hit high into the air" , "Upper region, empyrean" .)
