I've just learnt that the word "Goodbye" originated as a contraction of the phrase "God be with ye."

God be with ye -> Godbwye -> Goodbye

See! Even then people used "b" to represent "be" and "w" to represent "with"! Contractions are clearly not a modern thing.

In the Star wars world, shouldn't they be saying "Foorbye"?

So nowadays, when we say "bye" when we are leaving each other, we really mean "be with you"?

If I just want you to scram, should I be saying "Debye"?(Wait, that's a unit for dipole moment)

Or if I wish you future success in your political career in Singapore, I should say "Leebye"?

I'llbye sounds pretty cryptic if you ask me.
