Is Administratium an actual word?

Question

We commonly use this word in office, and the definitions point to its meaning.

But is this an actual word? It's not in the Oxford English Dictionary.

Answer 1

Flooglepz is a word: I just invented it. Until a few seconds ago I was the only person who used it and knew of it.

A few more people know about the word administratium.

Neither of these words are generally accepted English words — however the set of words that are considered English words is not a set with clear undisputed boundaries. Personally, if it’s in the OED, I’ll consider it an official English word, and if it isn’t I won’t. In the next edition of OED, administratium might conceivably make the transition from a joke word used by a few people to a joke word used widely enough to become an English word (by my definition).

Answer 2

If you google it, Wikipedia (http://en.wikipedia.org/wiki/Administratium) says

Administratium is a well-known joke in scientific circles...A similar joke concerns Administrontium which was referenced in print in 1993"

Although the points above about relation to population are accurate.

Answer 3

I would say that it depends on the population. The question "Is x a word" is meaningless without reference to a population. If the population is taken as your office coworkers, then yes it most definitely is a word. For larger populations, I would say that it is not a "real" word.
