Yes, case systems are an example of this. Most Indo-European languages use some combination of fixed word-order, noun classes (aka gender), and case systems to compensate for errors in communication.
English for example has a relatively strict word order.
Keep in mind that linguistic drift was a much stronger force in the past than it is today and being able to infer meaning through some incomprehensible input was a very important feature for languages to have.
>I guess the extensive case system for example, which allows to omit agent noun since the information is contained in the verb, but in reality is rarely omitted.
Is this just in the written form or also when spoken? Spoken language is much more susceptible to comprehension errors.
