I was just wondering if it is okay to use definitions from Wikipedia on my website for the main content on some of my pages. I think that it should be allowed since it is a dictionary and it is supposed to be a reference. Anyways, is it legal? and if so, do I have to give credit to Wikipedia? For example: Defintion of Door: etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc.etc. etc. etc. Defintion by Wikipedia
