Boozer visited by earl in Paddington? (4)
I believe the answer is:
bear
'paddington?' is the definition.
(Paddington Bear is an example)
'boozer visited by earl' is the wordplay.
'boozer' becomes 'bar'.
'visited by' indicates putting letters inside.
'earl' becomes 'e'.
'bar' placed around 'e' is 'BEAR'.
'in' is the link.
(Other definitions for bear that I've seen before include "Massive mammal" , "Hold up" , "It could be polar or grizzly" , "Large carnivore" , "eg Pooh" .)
