What appears after the word when a footnote is added?

When a footnote is added to a document, a reference marker in superscript appears next to the word that the footnote is associated with. This superscript number or symbol serves as an indicator, pointing the reader to additional information or a citation that is provided in the footnote at the bottom of the page or at the end of the document. The use of a superscript format helps maintain the flow of the main text while clearly signposting that there is supplemental content available for clarification or reference. This is a common practice in academic and formal writing to facilitate a clearer understanding of the text without overwhelming it with citations or explanations.
