Trade languages vs court languages ?

Hello there,

I wanted to read more about something I was told in high school but never looked up myself. I tried to google search it without success. I probably remember wrong and have the wrong keywords.

The idea was that Portuguese, French, Spanish and Italian were languages constructed in courts which had the main objective to please the king. This had the consequence that the language was more flexible for double meaning. If the king was displeased with what he understood you could just say that you meant the opposite because of that flexibility in the way it is phrased.

On the opposite, English, German, Danish are languages built on trade and market culture efficiency so the language is very effective conveying ideas without double-meanings.

Apologies for mistakes, english is my second language.

Does that ring a bell to anyone? I'd like to read more about that.
