German is a good language for arguments because it is very precise. In German the same and the same are not the same and absolutly not the same. (auf deutsch ist das selbe und das gleiche nicht das gleiche und absolut nicht das selbe)
Precision of a language is a subjective metric. In general, any language that borrows most foreign nouns and verbs can add nuances to its expressions, and thus become more precise.
This adoption rate depends on how many people speak both languages on a regular basis.
