Annoying or boring (7)
I believe the answer is:
irksome
I believe this is a double definition.
'annoying' is the first definition.
(I've seen this in another clue)
'boring' is the second definition.
(I know that boring can be written as irksome)
(Other definitions for irksome that I've seen before include "Tiresome, irritating" , "Bothersome, annoying" , "Troublesome, vexing" , "Tediously annoying" , "bugging" .)
