Hello. As suggested by @Pppery in T291737, we have decided to translate the 3 remaining namespaces on arywiki and their corresponding talk namespaces.
TimeText => سوتيتر
Talk namespaces (defined by adding لمداكرة د to the corresponding namespace):
TimedText Talk => لمداكرة د سوتيتر
The discussion to reach consensus on the translations to Moroccan Darija is located here: https://w.wiki/AiaQ
This is not an urgent task as we don't use these namespaces for now, and may actually never use them, so it's more for the sake of completeness. I can take care of creating a patch in Mediawiki core just as I did for the other namespaces on arywiki.
