Fish on ice? (5)
I believe the answer is:
skate
This clue could be a double definition.
'fish' is the first definition.
(skate is a kind of fish)
'ice?' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'on' is the link.
Can you help me to learn more?
(Other definitions for skate that I've seen before include "Ice --; roller --" , "move around ice" , "Glide on ice; ray" , "Runner" , "Food fish" .)
