since I don't have money - Dependent clause (subordinate clause): This clause provides additional information but cannot stand alone as a complete sentence. It functions as an adverbial clause, indicating the reason for not buying anything.
She did not travel - Independent clause (main clause): This is a complete sentence.
because she had no money - Dependent clause (subordinate clause): It functions as an adverbial clause, explaining the reason for not traveling.
He ate the whole hamburger - Independent clause (main clause): A complete sentence expressing a full thought.
even though he was full - Dependent clause (subordinate clause): This clause functions as an adverbial clause, providing a contrast or concession to the main clause. It explains the unusual action of eating when he was already full.
