Categories and Swadesh numbering have not been added here, but they could be added from the Wiktionary:Basic English template pages once the categories there were completed (or if the Swadesh numbers were needed here (especially to be able to re-sort the list to be able to add to or add from the Indo-Iranian Swadesh page once one was completed)).
Tip: There is a tool at http://www.wandel.subnet.dk/arabic.html which should help you to find the HTML codes for the Arabic script, if you are familiar with the script. (This should not replace the romanized versions, however.)
