# Custom text to enumerate items

I would like to know how one can create a list in which each item is enumerated with some custom text, like in the following picture.

I'm not asking how can one construct a list in which every member is of the form (Sn), for n a natural number, but rather how to create a list in which we could determine each item with any customized expression. I have no clue how one could implement this without manual alignment and spacing, so any help will be appreciated.

• @Akerbeitz I do not exactly understand your question. Do you want all items to be enumerated with the same number? Do you want to modify the enumerate counter? Or what? Please include a MWE. – Denis Sep 13 '20 at 2:15
• I have rewritten the whole question... please let me know if its still unclear what I am asking for. – Akerbeltz Sep 13 '20 at 7:24

Since you mentioned

how to create a list in which we could determine each item with any customized expression

I have used the optional argument if \item in order to manually determine the corrensponding label. I have also used enumitem to make sure the label is bold:

\documentclass{article}
\usepackage{enumitem}
\usepackage{lipsum} % Just for dummy text using the \lipsum command. Do not use in actual document.
\begin{document}

\begin{enumerate}[font=\bfseries]
\item[(S1)] \lipsum[1][1]
\item[(S2)] \lipsum[4]
\item[xyz] \lipsum[2][3]
\end{enumerate}
\end{document}
