# Underlined labels in the description environment

How can the description environment be modified so that it uses underlined labels instead of the default bold texts? It would be better if I can do that globally not just for one time.

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – BambOo Sep 2 '18 at 15:59

Redefine \descriptionlabel:

\documentclass{article}

\renewcommand{\descriptionlabel}[1]{%
\hspace{\labelsep}\normalfont\underline{#1}%
}

\begin{document}

\begin{description}
\item[abc] def
\item[ghi] lmn
\end{description}

\end{document}


Please, note that underlining is not a good typographic device.
