Which term identifies the function that shows how a dependent clause relates to the main clause, often exemplified by 'because', 'if', and 'since'?

• A. Subordinating conjunction
• B. Coordinating conjunction
• C. Preposition
• D. Adverb

Answer: (A)

Subordinating conjunction is the term for the word that shows how a dependent clause relates to the main clause. Because, if, and since introduce clauses that cannot stand alone and express relationships like cause or condition to the main idea. This contrasts with coordinating conjunctions, which join two independent clauses; prepositions link nouns to other words without creating a dependent clause; and adverbs modify verbs or adjectives and may signal time or manner but don’t serve to connect a dependent clause to the main one.
