I often hear the first part of the word Wikipedia mispronounced as if the word was Wiccapedia. The name Wikipedia is a portmanteau of wiki, a type of collaborative website, and encyclopedia. Wiki is pronounced /ˈwɪki/ or, /ˈwiːki/; wicca is pronounced /wɪkə/. (For those of you who don't know how to read IPA keys, wiki is pronounced wicky, and wicca is pronounced wika.)

This is an important distinction, because they are two completely different things. To clarify, this is Wikipedia:
