Something for a cuckoo to land on? (5)
I believe the answer is:
cloud
'land on?' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for cloud that I've seen before include "Make unclear" , "E.g. stratus" , "Dull spot" , "Eg, cumulus" , "''I wandered lonely as a ...'' (Wordsworth)" .)
