Latex

\par is a command used to indicate the end of a paragraph. It is equivalent to leaving a blank line between paragraphs. Here’s how it works:

This is the first paragraph.\par
This is the second paragraph.

Using \par explicitly is often unnecessary because LaTeX automatically starts a new paragraph when it encounters a blank line in the source code. However, \par can be useful in macros or environments where a blank line might not be feasible.
