If you're looking to simply format a glossary (not
automatically generate one), you can use hanging indents.
Hanging indents make the first line stick out to the
left, and the subsequent lines are indented.
Help has a good summary of how to do this. Then after you
get one glossary entry styled the way you want, you can
use the Format Painter button to quickly copy that
formatting to the other entries.
