[Star Wars] Is there any connection between Tatooine and Dantooine? Is -tooine a meaningful suffix in the Star Wars galaxy?

It's a meaningful suffix, but no one is exactly sure what the meaning is.  It's pretty common, especially in Legends.  It's thought to be named after an old Rakkata trade route, but no one knows if it has a meaning in Rakkatan, if Tooine is the name of the trade route, or if the Rakkata naming them just liked the sound.  It's also possible that Tatooine came first, with it's suns being named Tatoo 1 and 2, and then other planets mapped shortly thereafter were named following a theme.
