I don't believe you can do precisely what you want in Word. You could,
however, use footnotes or endnotes. When you hover over the reference mark,
the contents of the footnote or endnote is displayed in a popup tooltip.

I am an adult literacy tutor and want to find out if I can make comments
show
up with no author or comment No. information? The idea is that a learner
hovers over a word and can see synonyms, alternate spellings etc, without
the
formatting info of the comment also showing up.

I use Word 2003 in XP.
