Wry, incongruous (6)
I believe the answer is:
ironic
I believe this clue is a double definition.
'wry' is the first definition.
(I know that wry can be written as ironic)
'incongruous' is the second definition.
(I've seen this in another clue)
(Other definitions for ironic that I've seen before include "Characterised by mildly sardonic wit" , "Perversely humorous" , "Suggesting the opposite for humorous effect" , "Paradoxically amusing" , "Wry, sardonic" .)
