How to prevent plugin from messing with permalink words

I too am having this issue, pronouns and some conjunctions are being stripped. I can’t tell if it’s by design.

This was driving me nuts, too. I love this plugin, but I’m not sure why everything else has options to turn on or off and yet this one is just kinda built-in and buried.

Anyways, it took some digging, but if you go to:
/wp-content/plugins/wordpress-seo/admin/class-admin.php

And look for the line:
add_filter( 'name_save_pre', array( $this, 'remove_stopwords_from_slug' ), 0 );

You can just comment it out like this:
// add_filter( 'name_save_pre', array( $this, 'remove_stopwords_from_slug' ), 0 );

…and the stop word filtering for slugs will no longer take place.

Sweet, thanks. I’ll give it a try but wish there were more documentation on exactly why this is done in the first place.
