Emperor's hearing complaint tavern ignored (5)
I believe the answer is:
titus
'emperor's' is the definition.
(I've seen this before)
'hearing complaint tavern ignored' is the wordplay.
'hearing complaint' becomes 'tinnitus'.
'tavern' becomes 'inn' (I've seen this before).
'ignored' indicates named letters should be taken away.
'tinnitus' with 'inn' taken out is 'TITUS'.
(Other definitions for titus that I've seen before include "Rom. emperor 79 to 81AD" , "good book" , "Only part of Shakespeare play" , "recipient of holy letter" , "- Andronicus (Shak.)" .)
