Crossword Genius

A vile tent - foul air (9)


I believe the answer is:


'air' is the definition.
('ventilate' can be a synonym of 'air')

'a vile tent foul' is the wordplay.
'foul' indicates anagramming the letters.
'aviletent' is an anagram of 'VENTILATE'.

(Other definitions for ventilate that I've seen before include "Let air enter and circulate" , "Fan" , "Expose to a current of fresh air" , "Superficial" , "Allow fresh air to circulate" .)

I've seen this clue in The Telegraph.
