Do Italians sing the traditional Happy Birthday song? If so what are the words to it?
Could I also say "buono compleanno". It seems like spanish: they have the word "bueno", but sometimes, they use "buen" before some words. I don't get it the use of it.
Doesn't it becomes "buon" when it appears before the noun it's modifying? That's the usage note I get on Wiktionary. That would work like in Spanish, as peteraasch says: "buen" if it goes before the noun, "bueno" if it goes after.
Yes some people say that apparently
We don't wish people a happy birthdate!!!??? We celebrate that day every year and not just the first one. http://dictionary.reverso.net/italian-english/compleanno
"Birthdate" would most often be "data di nascita". http://context.reverso.net/translation/english-italian/birthdate
