The main idea here is how prefixes convey position. hypo- means below or under. In hypoglossal, glossal refers to the tongue, so hypo- + glossal literally means under the tongue. That’s why this prefix is used to indicate below—the term even names the nerve that travels beneath the tongue to innervate tongue muscles. The other prefixes don’t convey a below relationship: hyper- means above or excessive, pan- means all, and nulli- means none.
