Element with its own copy? (6)
I believe the answer is:
carbon
'own copy?' is the definition.
'carbon' can be an answer for 'copy?' (as in a carbon copy). I'm unsure of the 'own' bit.
'element with its' is the wordplay.
'element' becomes 'Ca' (Ca is an example).
'with' means one lot of letters go next to another.
'its' becomes 'rbon' (I can't explain this - if you can you should give a lot more credence to this answer).
'ca'+'rbon'='CARBON'
Can you help me to learn more?
(Other definitions for carbon that I've seen before include "Common element" , "------ copy: exact image; clone" , "This paper is used to make copies" , "Element in coal and diamonds" , "Element in soot, charcoal, etc" .)
