Burning issue with news leaving small rest room (8)
I believe the answer is:
lavatory
'rest room' is the definition.
(thesaurus)
'burning issue with news leaving small' is the wordplay.
'burning issue with' becomes 'lava' (I can't explain this - if you can you should give a lot more credence to this answer).
'news' becomes 'story' (story is a kind of news).
'leaving' indicates named letters should be taken away.
'small' becomes 's' (abbreviation - e.g. clothes size).
'story' with 's' taken out is 'tory'.
'lava'+'tory'='LAVATORY'
Can you help me to learn more?
(Other definitions for lavatory that I've seen before include "Ladies or Gentlemen" , "John for American" , "somewhere to go?" , "Toilet" , "one's flushed" .)
