In Bulgaria what do the words zdraveyte and zdrasti mean?

When meeting someone, Bulgarians usually shake hands. Formal greetings include Kak ste? (How are you?) or Zdraveite (Hello). The informal equivalents, Kak si? and Zdrasti or Zdravo (Health), are used among friends, relatives, and colleagues. Other phrases include Dobro utro (Good morning), Dobar den (Good day), Dobar vetcher (Good evening), or Leka nosht (Good night).

My search on zdraveyte shows that this is a geranium or a wedding bouquet thrown on the ground as the bridal couple walks over.

I was reading the title of a website, and along side zdraveyte was the French word 'bonjour' which means hello in English, and along side zdrasti was the French word 'adieu' which means goodbye in English, so the answers could be 'hello' and 'goodbye'.

"Zdraveyte" means hello in Bulgarian and it is derived from zdrave, which means health. Etymologically "zdraveite" means "be healthy".
"Zdrasti" is a shortened, familiar form and is equivalent to "hi" in English.

to Kainantu: The word for geranuim is very similar to what you found but it's "zdravetz". It was called so because it was believed to bring health to people.
