A bother; inconvenience (8)
I believe the answer is:
nuisance
I believe this is a double definition.
'a bother' is the first definition.
(I know that nuisance is a type of bother)
'inconvenience' is the second definition.
(I've seen this before)
(Other definitions for nuisance that I've seen before include "Bothersome annoying person" , "One causing annoyance" , "It causes inconvenience or annoyance" , "Trouble" , "Source of annoyance or aggravation" .)
