change permalinks of category

hello in my blog https://koungeek.com/ i have categories that have /cataegory/ in the permalink which i think looks ugly since my blog isn’t in english how can i edit that or even delete it ?
here’s is an example :https://koungeek.com/category/%d8%a8%d8%b1%d8%a7%d9%85%d8%ac-%d9%85%d8%ac%d8%a7%d9%86%d9%8a%d8%a9/
