Say silver piece (7)
I believe the answer is:
element
This might be a double definition.
'say silver' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'piece' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for element that I've seen before include "Basic chemical unit" , "Ingredient - small amount" , "He, say" , "eg Fire, air" , "Singular ingredient" .)
