Does it float through the air? (8)
I believe the answer is:
seaplane
'air?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for seaplane that I've seen before include "Marine aircraft" , "Floating aircraft" .)
