Irritating smoke circulating beside uncovered fire (7)
I believe the answer is:
irksome
'irritating' is the definition.
(I've seen this before)
'smoke circulating beside uncovered fire' is the wordplay.
'circulating' indicates anagramming the letters.
'beside' means one lot of letters go next to another (I've seen this in other clues).
'uncovered' says to take the centre.
The central letters of 'fire' are 'ir'.
'smoke' is an anagram of 'ksome'.
'ksome' after 'ir' is 'IRKSOME'.
(Other definitions for irksome that I've seen before include "'Tedious, tiresome (7)'" , "Tediously annoying" , "Smokier (anag.)" , "Bothersome, annoying" , "Burdensome and tedious" .)
