What do you mean, The Celtic cross?

[Dan Diffendale]

By Hercules Magusanus, how I love the online Sumerian lexicon... 8)

I'm glad to have been a (small) part of it... 8)

But in any case, you're right, there's no meaning of gal in Sumerian that means "people."

You know, what mean this word: Gall. In Hungarian: Celtic/Keltoi.
This GALL word original sumerian. Meaning: The People. Irish language: GAOL.

Vallus, by your method, the Celts were all terribly bitter because they had skin abrasions, because that's what "GALL" means in English!

Languages change through time. Words change. How easily can you read the 12th century Hungarian in Halotti beszéd?

I'm sure you can read it, but look at how different some of the words are, and that's in 800 years. Imagine how much different things would look over 3000 years, from the death of spoken Sumerian until today!
