In unicode-math-table.tex there is a line: \UnicodeMathSymbol{"02AA5}{\gla }{\mathrel}{greater-than beside less-than}% I don't know why the macro is called \gla here, but I would be even more critical of the expex package for its use of short macro names for complicated tasks. The risk of a clash with another package, using the same name quite naturally for a symbol (as here) or letter o in a foreign language, is just too great. I'd object to all these macro names in your example: \pex \a \gla \glb \glc \xe and the \begingl \endgl should be done as \begin{gl} and \end{gl} else there can be complications when combined with other LaTeX environments. Furthermore, I'd advise against it being accepted at CTAN until these issues are fixed properly. > > \begin{document} > > \pex > \a > \begingl > \gla mea mater sus mala est / > \glb my mother pig bad is / > \glc{‘my mother is a bad pig’} > \endgl > \a > \begingl > \gla mea mater sus mala est / > \glb wander mother pig apple eats / > \glc{‘wander, mother, the pig is eating the apples’} > \endgl > \xe > > \end{document} Now having said everything above, your easiest workaround is to adjust the preamble as follows: >> \documentclass{article} >> \usepackage{fontspec} >> \usepackage{unicode-math} >> \let\gla\relax >> \usepackage{expex} or as >> \documentclass{article} >> \usepackage{fontspec} >> \usepackage{expex} >> \let\expexgla\gla >> \usepackage{unicode-math} >> \let\gla\expexgla At least one of these should work to skip over the problem, provided you do not also want to use \gla as a math character. Other macro names may need to be treated similarly.
