When it comes to style and usage, there are no strict rules. Not grammatical errors per se, stylistic usage issues are deemed faulty.

The major usage issue in Turkish is the redundancy of expression. In rhetoric, a redundancy may also be called a tautology or a pleonasm.

To make sense, a statement must be both syntactically acceptable and semantically meaningful. Semantic errors have to do with meaning.

Among the biggest usage issues in Turkish writing is the redundancy, including by ‘padding’ sentences with extraneous expressions.
