Element iodine injecting mother of Oscar? (6)
I believe the answer is:
osmium
'element' is the definition.
(osmium is a kind of element)
'iodine injecting mother of oscar?' is the wordplay.
I cannot really see how this works, but
'iodine' could be 'i' ('I' can be a synonym of 'iodine') and 'i' is located in the answer.
'mother' could be 'mum' (mum is a kind of mother) and 'mum' is present in the leftover letters.
'of' could be 'o' and 'o' is found in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for osmium that I've seen before include "Heaviest substance known" , "Lustrous, extremely hard member of the platinum metals group" , "Densest of all naturally occurring metallic elements, Os" , "The heaviest metal known" , "Metal, the densest natural element (symbol Os)" .)
