Stays above water, till supplies appearing (6)
I believe the answer is:
floats
'stays' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for floats that I've seen before include "Rests or drifts on the surface" , "Stays on the surface of water" , "Stays on the surface of liquid" , "Hovers" , "Rests or moves on the surface of liquid" .)
