disclaimer: I am very new for LaTeX, so please do not redirect me to documentation, I read carefully several times ExPex PDF guide (http://mirrors.ibiblio.org/CTAN/macros/generic/expex/expex-doc.pdf) and was unable to achieve what I needed.
Below is sample text which uses ExPex module:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T2A]{fontenc}
\usepackage[russian]{babel}
\usepackage{expex}
\title{Glossary}
\usepackage{natbib}
\usepackage{graphicx}
\begin{document}
\maketitle
\ex[glstyle=nlevel,glneveryline={\bf,\it},glwordalign=center,exnoformat=X,exno=,glspace=1em,glwidth=5in,
,extraglskip=8pt]
\begingl
Abc[Abc]
def[def]
hij.[hij.]
\endgl
\xe
\end{document}
Which renders to this representation:
The maximun I was able to change font style: bold or italic, but not font size. But I need to contol font size. Thank you.
