One of the overheads, like cotton wool (5)
I believe the answer is:
cloud
This might be a double definition.
'one of the overheads' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'cotton wool' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'like' is the link.
Can you help me to learn more?
(Other definitions for cloud that I've seen before include "Condensed air vapour" , "It hides the sun" , "Become gloomy" , "Obscure" , "Visible vapour in sky" .)
