Space between label and subexample with Linguex

Question

I cannot increase the horizontal spacing between the label and the subexample, which is problematic with large grammaticality judgments.

\documentclass{article}
\usepackage{linguex}
\begin{document}
\setlength{\Exlabelsep}{3em}
\setlength{\Exlabelwidth}{2em}
\ex. Main level
\a. Sublevel
\a. Subsublevel1
\b. Subsublevel 2
\b. **Subsublevel 3
\end{document}

Answer 1

I think the lengths you're looking for are \SubExleftmargin and \SubSubExleftmargin:

\documentclass{article}
\usepackage{linguex}
\begin{document}
\setlength{\Exlabelsep}{3em}
\setlength{\Exlabelwidth}{2em}
\setlength{\SubExleftmargin}{3em}
\setlength{\SubSubExleftmargin}{3em}
\ex. Main level
\a. Sublevel
\a. Subsublevel1
\b. Subsublevel 2
\b. **Subsublevel 3
\end{document}
