This has been discussed with the community here https://ms.wiktionary.org/wiki/Wiktionary:Kedai_Kopi#Penukaran_ruang_nama_dan_tajuk_tab_%22Wiktionary%22_ke_%22Wikikamus%22
We are requesting the namespace Wiktionary to be renamed to Wikikamus.
Also, currently on browser's tab, "Wiktionary" also appeared in the tab title. For example, apple – Wiktionary. We want this to be renamed into Wikikamus as well.
Thank you
