The other day I discovered that the Hungarian word szia [sijɑ], which is used as a informal hello and goodbye, like ciao in Italian and ahoj in Czech and Slovak, possibly comes from the English expression ‘see you’ / ‘see ya’, at least that’s what a Hungarian friend believes. I hadn’t noticed the similarity between the two phrases before, and if I had, I would have assumed that it was a coincidence.

Another possible origin for this word is the Austria greeting/parting word servus, which is written szervusz in Hungarian, and which somehow became szia. This is the etymology given by Zaicz Gábor in the Etimológiai szótár (Etymology Dictionary) according to this discussion.

Does anybody know more about the origins of this word?
