Automatically remove repeated words in slug.

Hi everyone, i am looking for a way to remove repeated words in wordpress slug.

let say my domain is ‘example.com’

and i have a category named ‘WordPress How To’

i have configured the permalinks to be ‘example.com/wordpress-how-to/’

then i want to create a post with the title “How To Create A Child Theme In WordPress”

then the permalinks will automatically generate this..

‘example.com/wordpress-how-to/how-to-create-a-child-theme-in-wordpress/’

since the words “wordpress,how,to” are repeated, how can i automatically remove those words when i insert the title.

i want the permalinks will autogenerate this…

‘example.com/wordpress-how-to/create-a-child-theme-in/’

it’s actually easy to just edit the permalinks by clicking the edit button.

but is there any functions.php code to make it autogenerated?
