Element seen to change after animation (9)
I believe the answer is:
manganese
'element' is the definition.
(manganese is a chemical element)
'seen to change after animation' is the wordplay.
'to change' is an anagram indicator.
'after' is a charade indicator (letters next to each other).
'animation' becomes 'manga' (I can't justify this - if you can you should believe this answer much more).
'seen' is an anagram of 'nese'.
'nese' put after 'manga' is 'MANGANESE'.
Can you help me to learn more?
(Other definitions for manganese that I've seen before include "Metal used in steel alloys" , "Hard grey metal, Mn" , "Element, symbol Mn" , "Metal used in steel making" , "Metallic element used in steels" .)
