Use {{Definition needed}} in the body of an article as a request for other editors to add a definition to text that assumes familiarity with a term. When the problem is not with [[WP:jargon]] or technical terms, but simply with the wording, one may use {{Clarify}} instead. For dealing with dubious information, please use one of the following: {{citation needed}}, {{Verify source}}, {{Dubious}} or {{Disputed inline}}; otherwise, {{Explain}} may be a good choice,
| Parameter | Description | Type | Status | |
|---|---|---|---|---|
| Title | 1titlereason | A brief reason for the tag. Because it may not be immediately apparent to other editors what about the tagged passage is in need of further explanation, a brief reason is generally helpful. The reason parameter displays when the mouse cursor is placed over the text the template inserts. | String | suggested |
| Date | date | An optional date parameter that records when the tag was added. If this template is added without the date parameter, the date parameter will be added soon after by a [[WP:BOT|bot]].
