{{defn}} (or manual <dd>...</dd> markup) that pertains to the {{term}}, usually at the top of the first one unless it only pertains to a specific definition.{{term}} and {{defn}} (i.e., between </dt> and <dd>), or inside {{term|content=...}} (<dt>...</dt>), or it will break the glossary (description list) markup.Inline (e.g. {{Crossreference}}) or after-content (e.g. {{More}}) note templates can be used inside definitions normally. The purpose of this template is prevent the excessive indentation of hatnotes at the top of the definition.
This template is not for inline crossreferences to other pages, or other forms of Wikipedia self-reference. For those, use {{crossreference}}. (This template does not use the CSS class selfref.)
When used with a multi-definition term, the definition in which the {{ghat}} appears must be manually numbered (usually 1 ..., as shown in the example below).
