What part of speech connects clauses, sentences, or words?

The answer is correct because a conjunction is a part of speech specifically designed to connect clauses, sentences, or words. Conjunctions can join two independent clauses, such as 'I wanted to go for a walk, but it was raining,' where 'but' is the conjunction linking the two clauses. They can also connect words or phrases, exemplified by 'I would like coffee and tea,' with 'and' connecting the two items.

Pronouns, while they can replace nouns to avoid repetition, do not connect clauses or sentences – their primary function is to stand in for a noun. Adjectives describe nouns and add detail rather than serving as connectors. Adverbs primarily modify verbs, adjectives, or other adverbs, providing information about how, when, where, or to what extent something happens, but they do not connect parts of speech in the way conjunctions do.
