Under a cloud, I sprinted out (4)
I believe the answer is:
rain
'under a cloud' is the definition.
I can't judge whether this definition defines the answer.
'i sprinted out' is the wordplay.
'sprinted' becomes 'ran' (I've seen this in another clue).
'out' is an insertion indicator.
'i' going into 'ran' is 'RAIN'.
Can you help me to learn more?
(Other definitions for rain that I've seen before include "eg A shower" , "Precipitation" , "Fall wetly" , "Cats and dogs?" , "Weather - shower" .)
