The one that is never spoken, but understood by everyone of every nation.

off course my mother language cause i start to know it since i was baby.. n now i feel all the language has it's own beautiful..... so that's why i wanna learn aother language as well..

for me, all languages will do. since it's not the language does matter but its the content does. for words are sharper than the swords. creates wounds that are invisible to the naked eyes itself and sometimes doesn't heal over time. a language from the heart is the best! =p

Haha, maybe you should ask: for you , what's the most beautiful foreign language?

my mother language which made me so beautiful
