I think we need to clarify on the distinction between language-specific glossaries and adding a term as a terminology -- the latter means that it will be added to all language-specific glossaries, while the prior is only adding to the glossary of a single language.

So I suggest to rewrite the related two sentences to state "adding to a language's glossary" (which should be "Suggesting" by the way, as standard users can only suggest and not directly add glossary terms), and then separately mentioning that adding as "Terminology" means suggesting to add to all languages.

Otherwise super nice contribution, just like today's work 🙌
