Drinking hole popular with additional number (3)
I believe the answer is:
inn
'drinking hole' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'popular with additional number' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'with additional' means one lot of letters go next to another.
'number' becomes 'n' (n can represent any number).
'in'+'n'='INN'
Can you help me to learn more?
(Other definitions for inn that I've seen before include "Hostelry, tavern" , "Roadhouse" , "English country pub" , "Resting place" , ". . . of the Sixth Happiness (film)" .)
