it
Switches text to an italicized style, traditionally used for emphasis or mathematical variables in legacy LaTeX documents.
Overview
Represents an older method for italicizing text that predates modern LaTeX font commands. While still functional, this command has largely been superseded by more semantic alternatives.
- Historically common in older LaTeX documents and templates
- Primarily used within math mode for variable names
- Generally recommended to use \textit{} or \emph{} in modern LaTeX documents
- Maintains compatibility with legacy documents and specific journal requirements
- Part of the basic font-switching commands from early TeX
Examples
Italicizing a mathematical term within an equation
E = mc^2 \text{ where ${\it c}$ is the speed of light}Distinguishing a mathematical set name
x \in {\it R} \text{ where ${\it R}$ is the set of real numbers}
