Which term refers to a word that joins sentences or clauses together?

The term that refers to a word that joins sentences or clauses together is "conjunction." Conjunctions serve as connectors within sentences, linking two clauses or phrases to create coherence and flow. For example, common conjunctions include "and," "but," and "or," which function to connect different ideas and maintain the logical relationship between them.

This joining function is crucial in professional communication as it helps to clarify relationships between ideas and improves the overall readability and understanding of written content. By using conjunctions effectively, a communicator can present information in a way that is organized and harmonious, enhancing the audience's comprehension and engagement.

In contrast, nouns identify people, places, or things; verbs indicate actions or states of being; and adverbs modify verbs, adjectives, or other adverbs to provide additional detail about the manner, degree, or frequency of an action. While all these parts of speech contribute to sentence structure and meaning, they do not serve the specific purpose of joining clauses or sentences that conjunctions do.
