Which of the following terms describes words and phrases like "in addition" and "therefore"?

The term that best describes words and phrases such as "in addition" and "therefore" is verbal transitions. These are specific types of words or phrases used to connect ideas and help guide the reader or listener through a piece of writing or speech. Verbal transitions improve coherence and flow, making it easier for the audience to follow the logic or progression of thought conveyed by the speaker or writer.

Synonyms refer to words that have similar meanings, but they do not serve the function of connecting thoughts or ideas, which is central to the definition of verbal transitions. Examples refer to instances used to illustrate a point, while conjunctions are words that specifically connect clauses or sentences (like "and," "but," or "or"), but do not encompass the broader category that includes transitional phrases that indicate relationships among ideas, such as cause and effect or addition.
