Ciao - what does that mean?

I sign off with the word "ciao" often and every now and then someone will ask me what it means. Today I looked it up on the world famous "Wikipedia" and we all know that if it is on Wiki then it is gospel. (wink) Here's what I discovered about the little word "ciao."

The word ciao (pronounced "chaow" /tʃao/) is an informal Italian verbal salutation or greeting, meaning either "goodbye" or "hello". Originally from the Venetian language, it was adopted by Italian and eventually entered the vocabulary of English and of many other languages around the world. In the Spanish-speaking world, it is spelled "chao". The word is mostly used as "goodbye" in Spanish and English, but in modern Italian and in other languages it may mean "hello", "goodbye", or both.

Tye out. Ciao.
