Hey BEBOP!
Great list! I can't vouch for many of the other languages, but the Argentinian one should read:
Felices Pascuas y Feliz Ano Nuevo
or
Feliz Navidad y Prospero Ano Nuevo (like in the Jose Feliciano song)
"Pascuas" is also used for Easter greetings, whereas "Navidad" is specifically Christmas.
(Sorry I can't write the apprpriate accent marks.)
To BEBOP and all of you, my dear friends:
MERRY CHRISTMAS!!!!!!!!!!!!!!!!!!!! in any language if the world!
Hugs from
Ted
