# Conflict with defining labels in enumerate

I use to have the issue that new paragraphs within proofs inside an enumerate environment would not be indented. To solve that, I added the following in my preamble:

\usepackage{enumerate}
\usepackage{enumitem}
\setenumerate{listparindent=\parindent}


Now, whenever I have a proof within an enumerate environment, new paragraphs of the proof are indented, as desired. However, I have a new issue: I can no longer change the labels for a particular enumerate environment. For example, if I have

\begin{enumerate}[label=(a)]
\item First item
\item Second item
\item Third item
\end{enumerate}


then it displays as

Now, I can change this if I write

\begin{enumerate}
\item[(a)] First item
\item[(b)] Second item
\item[(c)] Third item
\end{enumerate}


and get the desired output:

But this can become quite cumbersome to remember which item number I am at and manually force a particular item to have the next desired label. What can I do in order to customize the labeling like you're usually able to do for a particular enumerate environment?

• Welcome to TeX.SE. Please use either enumerate or enumitem, not both of them.

• Why should I use only one of the packages? Do they conflict with each other? And no, I have not heard of that feature. Jan 26 '17 at 15:19
• Well, both define enumerate etc. environments, so loading one after the other one will necessarily disable the features of the previous one. If you need the features of enumerate and want to use enumitem, load \usepackage[shortlabels]{enumitem} and omit the enumerate package

• Ah I see. Thank you! Even though I resolved this issue, do you know what may have caused the label=(a) to stop working? Jan 26 '17 at 19:32

Solved my own problem! I just needed to use label=(\alph*) in place of label=(a). The counter would work just fine when I used label=(a) in the past, so I never had to think abut using label=(\alph*) in its place, until now.
• great work! you might also note that you can remove the enumerate package Jan 26 '17 at 16:50
• @cmhughes Thanks. Do you know what may have caused label=(a) to stop working? Jan 26 '17 at 16:56
