I want to indent from the second line.
I want to write in LaTeX something like this:
Lorem ipsum dolor sit amet, consectetur a
When you create a list the list margin is indented by one indent (\leftmargini) and \itemindent is 0; if you set the \itemindent equal to the negative of the left margin, the hanging indent will line up exactly with the outer scope margin, and you'll get exactly one indent inside the list. It is a quick and simple way to get in and out of a hanging indented list setting only one value: \itemindent.
\documentclass{article}
\usepackage{lipsum}
\begin{document}
\begin{list}{}{\setlength\itemindent{-\leftmargin}}
\item \lipsum[1]
\item \lipsum[2]
\end{list}
\end{document}
