Poet with his own Inn in London? (4)
I believe the answer is:
gray
'poet' is the definition.
(18th-century poet Thomas Gray)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for gray that I've seen before include "dull for Americans" , "(Churchyard) Elegy poet" , "In America, dull" , "a bit gloomy for the Americans" , "Author of ballad opera" .)
