State of coma? No! (6)
I believe the answer is:
monaco
'state' is the definition.
(Monaco is an example)
'of coma? no' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'coma'+'no'='comano'
'comano' is an anagram of 'MONACO'.
(Other definitions for monaco that I've seen before include "Constitutional monarchy on the French Riviera" , "Med principality" , "Second smallest sovereign state" , "Small European country" , "Home of the Grimaldis" .)
