Highest form of architecture? (4)
I believe the answer is:
roof
'architecture?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'highest form of' is the wordplay.
'highest form' becomes 'ro' (I can't justify this - if you can you should believe this answer much more).
'ro'+'of'='ROOF'
Can you help me to learn more?
(Other definitions for roof that I've seen before include "Part of mouth" , "Cover for house" , "Protective covering on top" , "Top of car/house" , "hit by someone in a temper" .)
