Style of architecture (6)
I believe the answer is:
gothic
'style of architecture' is the definition.
(Gothic is an example)
This is the entire clue.
(Other definitions for gothic that I've seen before include "Style between Romanesque and Classical" , "Of architecture with flying buttresses, for example" , "Style of architecture - ornate typeface" , "Lurid - style of European architecture" , "horrifying" .)
