+## Audiences and languages
+
+We have audiences that need to be addressed in their own language in along three axes:
+1. Level of Understanding: we currently use three levels of understanding
+2. Languages: e.g. Switzerland has four languages
+3. Jargon: language specific for field of expertise
+
+### Design principle
+We stick to one language in the most specific (or most elaborate definition of a term) for the source.
+
+Jargon needs a separate term definition to specify the term that covers a know concept for an inner circle but is unknown to the outside world.
+
+We use AI tools to translate to more general language for a lower level of understanding in the line of work or the mental model.
+
+We use AI tools to translate to a different language from the source language. E.g. English -> German & French & Italian. Why?: because it's a lot of work to maintain terms definitions in four languages by hand and have every single term definition still cover the same concept. 
+
+We always generate a link to the original, most elaborate, source in the base language. Why?: to back your AI-generated translations with the human-curated source.
