Redundancy in a natural language is not necessarily a bug. It can be considered a feature. Speach is transmitted over a noisy channel (as everybody knows who has ever tried talking/screaming to a friend on a busy street or a concert), so needs to contain redundancy for error correction purposes. A lot of that is context (there are only a handful of things my friend could be screaming at me at a given point in time), but a lot is that it's enough to hear parts of a sentence to infer what it's about.

Many different contexts make use of this redundancy. Air traffic communications is another example where synonyms are chosen to minimize misunderstandings yet still be concise.

Minimizing redundancy also minimizes synonyms, which can be undesirable. Another example is poetry.
