Natural environment for silver? (7)
I believe the answer is:
element
This clue could be a double definition.
'natural environment' is the first definition.
'element' can be an answer for 'environment' (element is a kind of environment). I'm not sure about the 'natural' bit.
'silver?' is the second definition.
(silver is a kind of element)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for element that I've seen before include "eg Fire, air" , "Component - habitat" , "lead, for example" , "An abstract part of something" , "Ingredient - small amount" .)
