Some paint on a coat such as this (8)
I believe the answer is:
intonaco
'as this' is the definition.
The definition suggests a singular noun which matches the answer.
'some paint on a coat' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'INTONACO' can be found hidden inside 'paint on a coat'.
'such' is the link.
Can you help me to learn more?
(Other definitions for intonaco that I've seen before include "finishing coat" , "surface for painting" .)
