Wordpress redirects non-existing url to existing ones - how to disable

Question

I've noticed that when I type:

http://domain.tld/c (which does not exist)

somehow, for some reason I'm directed to

http://domain.tld/contact (which exists)

I found that this is default behavior at least in recent versions of Wordpress.

How to control-disable this?

This question is a duplicate of Disable ONLY URL auto complete, not the whole canonical URL system

Try this filter

function remove_redirect_guess_404_permalink( $redirect_url ) {
if ( is_404() )
    return false;
return $redirect_url;
}

add_filter( 'redirect_canonical', 'remove_redirect_guess_404_permalink' );
