Shelter from the rain, no doubt (3)
I believe the answer is:
inn
'shelter' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'from the rain no doubt' is the wordplay.
'from' indicates a hidden word.
'INN' can be found hidden inside 'rain no doubt'.
Can you help me to learn more?
(Other definitions for inn that I've seen before include "Hostelry, tavern" , "Country pub, often with accommodation" , "Local" , "Swiss river" , "watering hole" .)
