Perl was originally named "Pearl". Wall wanted to give the language a short name with positive connotations. It is also a Christian reference to the [[Parable of the Pearl]] from the Gospel of Matthew.<ref name="long"/><ref>{{Cite magazine |date=2016-03-07 |title=Scripting on the Lido Deck |url=https://www.wired.com/2000/10/cruise/ |access-date=2023-02-14 |magazine=Wired|archive-url=https://web.archive.org/web/20160307004219/https://www.wired.com/2000/10/cruise/ |archive-date=March 7, 2016}}</ref> However, Wall discovered the existing [[PEARL (programming language)|PEARL]] language before Perl's official release and dropped the "a" from the name.<ref name="richardson1999">{{cite journal|last=Richardson|first=Marjorie|date=1999-05-01|title=Larry Wall, the Guru of Perl|url=http://www.linuxjournal.com/article/3394|url-status=live|journal=[[Linux Journal]]|archive-url=https://web.archive.org/web/20130720013904/http://www.linuxjournal.com/article/3394|archive-date=July 20, 2013|access-date=2011-01-03}}</ref><ref name="long"/>

The name is occasionally expanded as a [[backronym]]: ''Practical Extraction and Report Language''<ref>{{cite book|last1=Schwartz|first1=Randal|url=https://archive.org/details/learningperl00schw_278|title=Learning Perl|last2=foy|first2=brian|last3=Phoenix|first3=Tom|date=June 16, 2011|publisher=O'Reilly Media, Inc.|isbn=978-1449313142|page=[https://archive.org/details/learningperl00schw_278/page/n27 4]|quote=Perl is sometimes called the "Practical Extraction and Report Language", although it has also been called a "Pathologically Eclectic Rubbish Lister", among other expansions. It's actually a backronym, not an acronym, since Larry Wall, Perl's creator, came up with the name first and the expansion later. That's why 'Perl' isn't in all caps. There's no point in arguing that expansion is correct: Larry endorses both.|author-link1=Randal Schwartz|author-link2=brian d foy|url-access=limited}}</ref> and Wall's own ''Pathologically Eclectic Rubbish Lister'', which is in the [[man page|manual page]] for perl.<ref>{{cite web|last=Wall|first=Larry|author-link=Larry Wall|title=perl - The Perl language interpreter|url=http://perldoc.perl.org/perl.html#BUGS|url-status=live|archive-url=https://web.archive.org/web/20130701050810/http://perldoc.perl.org/perl.html#BUGS|archive-date=July 1, 2013|access-date=2011-01-26|work=Perl 5 version 12.2 documentation}}</ref>
