Editing Star polygon (section)

==Names==
Star polygon names combine a [[numeral prefix]], such as ''[[wikt:penta-|penta-]]'', with the [[Greek language|Greek]] suffix ''[[wikt:-gram|-gram]]'' (in this case generating the word ''[[pentagram]]''). The prefix is normally a Greek [[Cardinal number (linguistics)|cardinal]], but synonyms using other prefixes exist. For example, a nine-pointed polygon or ''[[Enneagram (geometry)|enneagram]]'' is also known as a ''nonagram'', using the [[Ordinal number (linguistics)|ordinal]] ''nona'' from [[Latin language|Latin]].{{citation needed|date=February 2015|reason=Do authoritative sources use both prefixes?}} The ''-gram'' suffix derives from ''[[wikt:γραμμή|γραμμή]]'' (''grammḗ''), meaning a line.<ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dgrammh%2F γραμμή], Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus</ref> The name ''star polygon'' reflects the resemblance of these shapes to the [[diffraction spike]]s of real stars.
