How to Insert Bold Text in LaTeX

You can write bold text in LaTeX by using the \textbf{} command. The text which should be bold goes between the { and } symbol. See the example in Listing 1 in which "and parts of it" will be rendered bold.

\documentclass{article}
\begin{document}
This is text \textbf{and parts of it} are bold.
\end{document}
