Vocabulary isn't just words, it's thought patterns. This is why (approximately) the Chinese have the same word/symbol for chaos as they do for opportunity.
You do not seem to understand this.
There are reasons for number patterns (for example) being culture specific. There are cultures in the world that do not have numbers for 'above 3' for example. There are cultures that count in 5's, 10's 12's etc. This is not random. There are reasons Romans had no zero in their concept of numbers.
Go tell the Chinese/many other cultures to 'invent new words'.
Your concept of language and vocabulary is ridiculously simplistic and elicits no understanding or idea of cultural phenomema or even etymology.
