Which part of speech typically connects two independent clauses in a sentence?

The correct answer is conjunction. Conjunctions are essential in sentence structure as they serve the primary function of connecting words, phrases, or independent clauses. When used in the context of connecting two independent clauses, they help to create complex and compound sentences, facilitating a smoother flow of ideas. A common example would be coordinating conjunctions like "and," "but," or "or."

In this case, when you want to combine two independent clauses into a single sentence to express a more intricate thought, a conjunction is required. For instance, in the sentence "I wanted to go for a walk, but it started to rain," the word "but" acts as the conjunction that links the two independent clauses. Understanding the role of conjunctions is crucial for crafting well-structured sentences that convey clear and connected ideas.
