| || সংক্ষেপে এই পৃষ্ঠাখন: Other people have to be able to check that you didn't just make things up. This means that all quotations and any material challenged or likely to be challenged must be attributed to a reliable, published source using an inline citation. |
The threshold for inclusion in Wikipedia is verifiability, not truth—whether readers can check that material in Wikipedia has already been published by a reliable source, not whether editors think it is true.
To show that it is not original research, all material added to articles must be attributable to a reliable, published source appropriate for the content in question, but in practice you do not need to attribute everything. This policy requires that all quotations and anything challenged or likely to be challenged be attributed in the form of an inline citation that directly supports the material. For how to write citations, see Citing sources.
This policy applies to all material in the mainspace—articles, lists, sections of articles, and captions—without exception, and in particular to material about living persons. Anything that requires but lacks a source may be removed, and unsourced contentious material about living persons must be removed immediately.
Verifiability is one of Wikipedia's core content policies, along with No original research and Neutral point of view. These policies jointly determine the type and quality of material that is acceptable in articles. They should not be interpreted in isolation from one another, and editors should familiarize themselves with the key points of all three. Articles must also comply with the copyright policy.
