Having no carbon in gold, carbon in silver brought up (9)
I believe the answer is:
inorganic
'having no carbon' is the definition.
I can't tell whether this defines the answer.
'in gold carbon in silver brought up' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'carbon' becomes 'C' (C is the chemical symbol for carbon).
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'brought up' is a reversal indicator (in a down clue, letters go up).
'c'+'in'+'ag'='cinag'
'cinag' backwards is 'ganic'.
'in'+'or'+'ganic'='INORGANIC'
Can you help me to learn more?
(Other definitions for inorganic that I've seen before include "Man-made" , "What can describe something alien to life" , "Not of animal/vegetable origin" , "Not deriving from living matter" , "Not derived from living matter" .)
