It kind of depends on which Galician "x" you are talking about. The one that is usually the equivalent of the Spanish "j", is pronounced basically like the English "sh". So, the word "xamón" (jamón) sounds like "shamón".

In old Castellano, the "x" existed in this sense too. That's why Mexico is spelled the way it is. It used to be pronounced something like "Méshico" (more or less) and the "x" was the only letter that adequately matched that sound. Today both México and Méjico are accepted, but the former is more common.

The "x" in words like "excelente" is pronounced the same as in Spanish.

Galicians can look like Irishmen... But honestly the northern looks are not all that different from the looks from Madrid or other parts of Spain. Geographicaly they are so near that it is almost grazy to suggest that their is a strong and lets admit here racial difference or as they say they are "Celts" and the Celts also were present well below modern Madrid.

If it did not say Galicia/Santiago it could be in my eyes from anywhere in Southern Europe. Also dont start with the Moorish stuff many of the Moors that invaded were Berbers.

A unified Celtic culture never really existed, though the peoples of Western Europe prior to the Roman conquest had some things in common, including an Indo-European language. It was the Greeks, perhaps, and then the Romans who began to classify the people on their frontiers under the handy term Gauls: - said to mean "foreigner". See how cognate all the following terms are: Gaul, Galatia (in Anatolia), Galicia (Spain), Galicia (Poland), Gael (as in Ireland and Scotland), Waloon (Belgium) and Wales.
The languages of Galicia and Asturias are derived from Latin, as is French (though not Breton) as these areas were assimilated into Roman or post-Roman, Christian culture. As such they have nothing in common with the "Celtic" languages which exist on the Atlantic seaboard such as Irish, Scottish or Welsh.
As for ethnicity, again, no "pure" Celtic people ever existed. This is a racist 19th century notion, whereby people were divided up into races. The English were particularly eager to expropriate the term British for themselves and thus classify their troublesome neighbours as "Celts".
Ethnically, if the people of Galicia and Ireland have anything genetic in common, it's likely to be a result of a marauding Viking in the 10th century!
Back to Galego and Portuguese. There's plenty in common, but political divergence - which I believe began when the dioceses of Braga (Portugal) and Santiago split after a row between bishops in the 9th century! - had much to do with the sister languages growing apart as they grew up. But they're still - the sisters that is, not the bishops - on speaking terms, so to speak.

The British are very Germanic they are mostly Anglo Saxon a Germanic people from Europe. People from Ireland,Scottlan,and Wales can sometimes be darker not all Irishmen are red haired and blue eyed some are actually dark haired and dark eyed so the British do have a slightly more "Germanic" character. Galician,Spanish,Portugues etc. all come from Latin an Indo-European language most European languages derive from this for example mother/madre/mutter/mae etc etc. this is the word for mother in English, German, Spanish and Portugues. father/padre/vatar etc. all are indo-European languages. Galician is derived from latin brought into Spain by the Romans no? But of course even though it developed right beside Castillian of course of course their is no realtionship at all between the languages of course it is all for political reasons LOL. The only non indo-European language on the Iberian peninsula is the Basque language. I believe Celts wre mainly a mix of indo-European and old-Europeans which is why the Scottish and Irish "Celts" are basically blood brothers to the Basque on the Y chromosones. I don't think their is a "Celt" race.
