Here's why:
* Subordinating conjunctions are single words like "because", "although", "since", "while", etc., that introduce a dependent clause and connect it to an independent clause.
* Conjunctive adverbs are phrases that connect two independent clauses, often used to show contrast, cause and effect, or sequence. Examples include "however", "therefore", "nevertheless", and "even though".
Example:
* Subordinating conjunction: *Because I was tired, I went to bed early.* ("Because" introduces the dependent clause "I was tired" and connects it to the independent clause "I went to bed early").
* Conjunctive adverb: *I was tired; however, I stayed up late to finish my work.* ("However" connects the two independent clauses, showing contrast).
Even though is similar to a subordinating conjunction in that it introduces a dependent clause, but it's a phrase rather than a single word.
