Technically, you can't say hello in Cyrillic because it is an alphabet used by several different Slavic languages like Russian and Ukrainian. I'll be happy to write out a few ways of saying "hello" in Russian using Cyrillic, though. :)
Привет - pri-vyet (used casually, basic equivalent of "hey" or "hi")
Здравствуй(те) - Zdrastvoy(tyeh) = hello (tack on the 'tyeh' to make it more formal)
Алло - Alo (how Russians commonly answer the telephone)
Transnistria has three official languages - Moldovan (basically Romanian written in cyrillic), Russian and Ukranian. Hence: Noroc! Privyet! Privit!
Iartă-mă. Romanian hasn't used the cyrillic alphabet for a very long time now.
You say "hello" in English.
Cyrillic is another name for Russian Alphabet.
STOP (cyrillic СТОП) or STOI (стой)
Bolj (ab BOL') In Cyrillic - БОЛЬ
Say Hello to Rosita!
Kamusta is how you say hello
halito is how you say hello and how to say hello how are you is Halito, Chim Achukma?
This is how you say hello in Turkish: Merhaba = Hello
Knyiga. Spells knjiga on latin and књига on cyrillic.
Crocodiles do NOT say hello.
