Under a cloud, I sprinted out (4)
I believe the answer is:
rain
'under a cloud' is the definition.
I can't tell whether this definition defines the answer.
'i sprinted out' is the wordplay.
'sprinted' becomes 'ran' (I've seen this before).
'out' means one lot of letters goes inside another.
'i' put inside '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" .)
