# Command using lettrine affects all paragraphs [closed]

I'm completely new to LaTeX. I found a template and it creates a command using the lettrine package:

%An initial of the very first character of the content
\usepackage{lettrine}
\newcommand{\initial}[1]{%
\lettrine[lines=3,lhang=0.33,nindent=0em]{
\color{gray}
{\textsc{#1}}}{}}


So I use it at the beginning of my chapter like this:

\chapter{Introduction}
\label{chap:100}

\initial{I}ndustry 4.0 is a wide...


The result is fine:

The problem is now, that all paragraphs within the chapter are affected as well, because the first three lines of each new paragraph, for example after a list, is indent.

If I don't use the "initial" command it looks fine.

The problem is, that even \noindent doesn't work. How can I deactivate this behaviour for the rest of the chapter?

• welcome to tex.se! that be more clear, that is your problem, please provide complete small document beginning with \documentclass{,,,} and ending with \end{document}. use `\letrine hasn't work with lists. – Zarko Aug 14 '18 at 11:25
• I can't reproduce the issue; please, make a compilable example. – egreg Aug 14 '18 at 16:38
