Almost new company providing plaster decoration (6)
I believe the answer is:
fresco
'plaster decoration' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'almost new company' is the wordplay.
'almost' means to remove the last letter (almost the whole word is kept).
'new' becomes 'fresh' (associated in meaning).
'company' becomes 'co' (abbreviation).
'fresh' with its last letter removed is 'fres'.
'fres'+'co'='FRESCO'
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for fresco that I've seen before include "Mode of wall painting" , "Painting using watercolours on plaster" , "Artistic work" , "Painting done in wet plaster" , "Mural painting" .)
