Just looking for ideas on how I would replace all of the instances of the word "Topic" with "Discussion" — for our audience it's a more clear word than "topic".

I thought of using String Overrides (https://www.drupal.org/project/stringoverrides) BUT I would have to override every single string that contains the word — wondering if there was a way to simply replace the word and not have to rewrite all of the strings.

Many thanks for any ideas.
