Dictionary is a dictionary module/component/plugin for PostNuke, Mambo, XOOPS and LDU. Firstly ported to PN by Edfel J. Rivera at neo.upr.edu from the original module created for PHP-Nuke. This module uses “The Online Plain Text English Dictionary” OPTED, a public domain English word list dictionary, based on the public domain portion of “The Project Gutenberg Etext of Webster’s Unabridged Dictionary” which is in turn based on the 1913 US Webster’s Unabridged Dictionary.
