Flash bag holding one’s artwork (6)
I believe the answer is:
mosaic
'artwork' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'flash bag holding one's' is the wordplay.
'flash' becomes 'mo' (both can mean a very short period of time).
'bag' becomes 'sac' (a small bag).
'holding' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'sac' going around 'i' is 'saic'.
'mo'+'saic'='MOSAIC'
Can you help me to learn more?
(Other definitions for mosaic that I've seen before include "Picture/pattern in small coloured pieces" , "Design made of small pieces of coloured stone or glass" , "Law of the Jews from Mt Sinai" , "Inlaid stone decoration" , "Inlaid work - of a Hebrew prophet" .)
