What Humphrey hung in the loo? (6)
I believe the answer is:
bogart
'loo?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bogart that I've seen before include "See 12" , "Humphrey --, US film actor" , "American actor" , "Rob gat from the old film star" , "Lauren Bacall's first actor husband, d. 1957" .)
