PRESTIGE - The asterisk
asterisk is used to call out a footnote, especially when there is only one on
the page. Less commonly, multiple asterisks are used to denote different
footnotes on a page (i.e., *, **, ***).
An asterisk (*; Late Latin: asteriscus, from
Greek: ἀστερίσκος, asteriskos, "little star") is a typographical symbol or
glyph. It is so called because it resembles a conventional image of a star.
Computer scientists and mathematicians often
pronounce it as star, or, more informally, splat.
In English, an
asterisk is usually five-pointed.
In many publications, the asterisk is employed as a shorthand to denote
the significance of results when testing hypotheses. When the likelihood that a result occurred by chance
alone is below a certain level, one or more asterisks are displayed.
