I have a site that is translated in English and French - can't change "Home" link in menu My entire Drupal 8 site has been translated except I can't find where to change the translation of the "Home" link. When the site is in French mode (with the /fr) all my menu items show the appropriate French translation except for "Home" which I would like to read "Accueil" when I've switched to French. 
Thanks for any insights.
Most likely, the "Home" menu link is coming from the UI text in Drupal Core.

You should be able to enable the "Interface Translation (locale)" module and then obtain .po or .pot files for the respective language (as described on the Drupal.org internationalization page). 

Refer to https://www.drupal.org/node/1814954 for information about editing the .po/.pot files and https://www.drupal.org/node/314231 for info about obtaining them.
