English teachers who do not understand the English language. The sentence was something like "During the Revolutionary War, some colonists wanted to break away from England, while others did not." My English teacher was trying to tell us that the dependent clause "while others did not" was also an adjective clause modifying the infinitive "to break" - no! Dependent clauses don't modify anything! And when I tried to explain this to her, she basically told me I was wrong and that she could understand why I was confused.
