Can I change the “listing” route in the ****.com/listing/**** url?

You have to use translation plugin ( Loco Translate ) to change the text. It’s from Add-Ons plugin.

Search for listing string then translate it, you can also change category, location and feature slugs by translate listing_cat, listing_location, listing_tag and listing_feature texts.

Read Theme and Plugin Translations for more details.

Then click to Save Changes button on Settings -> Permalinks screen.

If you are using WPML for multilingual site, follow this guide: Translating Page Slugs
