These features are allowing to build more complex sentences using less words and&#x2F;or make them shorter.
After translating of thousands of sentences from English to my native language for opensource projects, I found that word-to-word translations are about 30% longer in average, while translations of sentences of text are about 10% shorter in average, sometimes even 3x shorter. Direct consequence is that it is easier to understand shorter text, because of limited size of short-time memory. I.e. shorter text adds few points to IQ.
