Quote:
The Greek word xenos means "stranger" or "alien" (in the sense of "foreigner")", the common name of the xenomorph (not to be confused with the name of unknown extraterrestrial life) and morphĂȘ means "form", a Greek term that should not be confused with the English "morph". In other words, the word xenomorph itself means little more than "alien form"


The Classical Greek god of dreams was named Morpheus. Perhaps "xenomorph" was meant to suggest a dreamlike alien.

I looked at my big print dictionary, and "morph" is defined as a linguistic term: "A sequence of phonemes constituting a minimal unit of grammar or syntax."

-morph, as a suffix, means, "the final element in a compound word."

So I guess it means whatever the writer who came up with it wants it to mean.
