Power of art excited Mackintosh (10)
I believe the answer is:
waterproof
'mackintosh' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'power of art excited' is the wordplay.
'excited' indicates anagramming the letters.
'power'+'of'+'art'='powerofart'
'powerofart' anagrammed gives 'WATERPROOF'.
Can you help me to learn more?
(Other definitions for waterproof that I've seen before include "Impermeable" , "Mac" , "Impervious to rain" , "Rain-resistant" , "Protective garment" .)
