I'm from Wales, and our native language is Welsh!
In Welsh, there isn't really a word for 'hello'
We use:
Bore da - Good Morning
P'nawn da - Good Afternoon
Noswaith da - Good Night
And just as a little side-word, this is the longest word in the Welsh language, it's the name of a train station:
Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch
Look it up if you don't believe me.
