Position right inside a cloud (7)
I believe the answer is:
stratus
This clue could be a double definition.
'position right' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'a cloud' is the second definition.
(stratus is a kind of cloud)
'inside' is the link.
Can you help me to learn more?
(Other definitions for stratus that I've seen before include "Large dark low cloud" , "Continuous cloud type" , "Cloud cover" , "Could carry rain" , "Grey cover" .)
