From which language does the word "wiki" come?

Wow. I learn something new every day!! My mother had a clever saying, "The day I stop learning something new is the day they throw dirt in my face!" LOL ;)

The first time I heard the word was at the Honolulu airport. The Wikiwiki Bus is the shuttle that goes between mainland and inter-island terminals. Hawaiian is a fun language.

It's also a "wiki-lamp"
