# Line break and hyphenation for underlined text

I am struggling with a problem that occurs using \underline. From other posts I heard that there is no possiblity for linebreaks using this command. However, I tried using the ulem package. In fact, line breaks are possible but hyphenation is not. So, I face another problem. I have a continuous text with some underlined parts of a sentence which need line breaks as well as hyphenation.

How am I supposed to solve this?

My code:

\usepackage[normalem]{ulem}
\begin{document}
\begin{itemize}[leftmargin=*]
\item There is an item:
\begin{itemize}

%using \underline
\item[] Lorem ipsum dolor sit amet, consetetur sadipscing
elitr, sed diam nonumy eirmod
\underline{thereIsAReallyLongWord in a senctence}
aliquyam erat, sed diam voluptua.

%using \uline
\item[] Lorem ipsum dolor sit amet, consetetur sadipscing
elitr, sed diam nonumy eirmod
\uline{thereIsAReallyLongWord in a senctence}
aliquyam erat, sed diam voluptua.
\end{itemize}
\end{itemize}
\end{document}


• Please make a complete MWE from your code. And the long word you are mentioning probably would not break as it is not a real word. If I set the hyphenation using \- at the appropriate positions line breaking works. – epR8GaYuh Mar 8 '18 at 10:33
• do you really have to use underlining (it is a typewriter convention rather rarely used in typeset material) ulem should work OK if you use hyphenatable text but if at all possible I would use a font change such as italic instead. – David Carlisle Mar 8 '18 at 10:36

It works with soul, but, please, don't use underlining.

\documentclass{article}
\usepackage{soul}

\begin{document}

\begin{itemize}
\item There is an item:
\begin{itemize}
\item Lorem ipsum dolor sit amet, consetetur sadipscing
%          elitr, sed diam nonumy eirmod
\ul{thereIsAReallyLongWord in a sentence}
aliquyam erat, sed diam voluptua.
\end{itemize}
\end{itemize}

\end{document}
