Popular name for a pub (3)
I believe the answer is:
inn
'a pub' is the definition.
(thesaurus)
'popular name' is the wordplay.
'popular' becomes 'in'.
'name' becomes 'n' (common abbreviation e.g. on forms).
'in'+'n'='INN'
'for' is the link.
(Other definitions for inn that I've seen before include "eg the Tabard" , "Swiss river" , "Possibly Jamaica" , "Drinking-place" , "One of Lincoln's" .)
