Surprised this hasn’t been mentioned yet, but:

doppelgu00e4nger noun
a ghostly double or counterpart of a living person.

What does hologram hologram look like? In common usage I’ve heard the word to most commonly mean a duplicate or replication intended to appear identical to the original even to the point of replacing the original. For example, if I don’t know both versions of the word, a duplicate should be checked and replaced with the original. In any case, a forgery is a similar physical thing. How is it different?

It doesn’t hold up as it added context relates to software objects. Is this particularly grating in a repeat-typing context? If I need to expose the real and fake objects through a user interface, I think it could work.

The literal translation of the word from German is double-goer or double-walker which works quite well for software term, reality-reflecting term, or a person-interface term.
