Human languages aren’t usually concerned with maximal information density though. Multiple layers of redundancy are often present. Features like noun verb agreement, grammatical gender, pleonasms, and even redundant words (last will and testament, vim and vigor etc) are used in various languages despite the redundancy, to increase clarity.

Pleonasm is more of a needless redundancy like "It's déjà vu all over again."
