Tedious smoker I put out (7)
I believe the answer is:
irksome
'tedious' is the definition.
(I know that tedious can be written as irksome)
'smoker i put out' is the wordplay.
'put out' indicates an anagram.
'smoker'+'i'='smokeri'
'smokeri' anagrammed gives 'IRKSOME'.
(Other definitions for irksome that I've seen before include "Tediously annoying" , "'Annoying, irritating or boring (7)'" , "Smoker I find annoying" , "Burdensome and tedious" , "bugging" .)
