Editors often have questions regarding notability. There is a difference between the English language definition of notability and Wikipedia's concept of notability. The Merriam-Webster dictionary defines notability as "unusual and worth noticing; very successful or respected".[1] Simple English Wikipedia's guideline is Wikipedia:Notability.
On Wikipedia, notability is a test used by editors to decide whether a subject can have its own article. With few exceptions, articles at Wikipedia need to be about notable subjects to be included. This is a basic standard to avoid Wikipedia's becoming a collection of everything. Article and list topics must be notable, or "worthy of notice". Determining notability does not necessarily depend on things such as fame, importance, or popularity. Those may help the acceptability of a subject that meets the guidelines. It is never enough to say a subject is notable. Notability must be shown with reliable source citations.
