Injected energy into a 3D representation (5)
I believe the answer is:
added
'injected' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'energy into a 3d representation' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mcd).
'into' is an insertion indicator.
'3d' becomes 'd'.
'representation' becomes 'dd' (I can't justify this - if you can you should give a lot more credence to this answer).
'a'+'d'+'dd'='addd'
'e' put inside 'addd' is 'ADDED'.
Can you help me to learn more?
(Other definitions for added that I've seen before include "Extra" , "Contributed" , "Totted" , "Appended; totalled" , "Said" .)
