* Pleonasm: This is the most technical term, referring to the use of more words than necessary to express an idea. It can be considered a form of redundancy, but it can also be used for emphasis or clarity.
* Tautology: This refers to a statement that says the same thing twice using different words. It can be seen as a type of redundancy, often used in formal writing for emphasis or to make sure a point is understood.
* Repetition: This is a broader term that encompasses both pleonasm and tautology, as well as other instances where words or phrases are repeated for emphasis, rhythm, or other stylistic purposes.
* Redundant language: This is a general term that can be used to describe any instance where words or phrases are unnecessary or repetitive.
* Wordiness: This is a term that refers to using more words than necessary to express an idea. It can be a symptom of redundancy, but it can also be a result of other factors, such as unclear thinking or a lack of confidence in one's writing.
Ultimately, the specific term you use will depend on the context of the speech and the desired effect.
