No gas here cooking coq au vin? Without question (2,5)
I believe the answer is:
in vacuo
'no gas here' is the definition.
(there is no gas in a vacuum)
'cooking coq au vin? without question' is the wordplay.
'cooking' is an anagram indicator.
'without' is a deletion indicator.
'question' becomes 'q'.
'coq'+'au'+'vin'='coqauvin'
'coqauvin' with 'q' removed is 'coauvin'.
'coauvin' is an anagram of 'IN VACUO'.
(Other definitions for in vacuo that I've seen before include "In a vacuum (Latin)" , "amid empty space" , "Not based on evidence (Latin)" , "Engulfed by emptiness" , "Unrelated to context" .)
