Redirect in .htaccess from one page to another?

Question

htaccess

Website on WordPress, added multilingualism with polylang.
Now many pages give 404 because the urls have changed. Added prefixes ru and uz .
from examplesite.com/page to examplesite.com/ ru /page .
That is, if you go to examplesite.com/page . Then everything works
. And if examplesite.com/ ru /page . Then 404
So I rummaged through the internet, everyone writes one thing - make a redirect in .htaccess
help with the redirect.
I need to redirect
from help.uz/ru/profile to help.uz/profile and
c help.uz/uz/profile to help.uz/profile

Answer 1

Solved the issue
just registered at the end
If there is a better option, please write. For example to make the domain dynamic.
So that some variable with the domain is substituted by itself http://%DOMAIN%/profile/

Read about RegularExpressions in htaccess. Then use something likeRewriteRule ^(.*)$ ^string(.*)$0 [R=301, L]
