gb4e center example text

Question

I'm writing an article with several short example sentences. The document as a whole would look better if my example sentences were horizontally centered rather than left-aligned. Of course, I still need the labels on the left. How can I achieve this? Here's a simple MWE:

\documentclass{article}
\usepackage{gb4e}
\begin{document}
\begin{exe}
  \ex This sentence is short.
\end{exe}
\end{document}

Answer 1

You need to use \hfill and \hfill\null:

Notes:

• The showframe package was used just to show the page margins. It is not needed in your actual use case.

Code:

\documentclass{article}
\usepackage{showframe}
\usepackage{gb4e}
\begin{document}
\begin{exe}
  \ex \hfill This sentence is short.\hfill\null
\end{exe}
\end{document}
