That she was the only one who came made a huge difference in our plans.

Is this a Sentence or a Clause Fragment?
I think it is a sentence but can somehow check my answer?

Here's the breakdown:

That she was the only one who came = a noun clause, serving as the subject of the sentence.

… made a huge difference in our plans = the complete predicate of this sentence (that is, the verb "made" and everything that goes with it).

Since it has a subject (noun clause) and a verb (complete predicate), it's a complete sentence.

Yes, the given text "That she was the only one who came made a huge difference in our plans," is a complete sentence. It has a subject ("she") and a verb ("was"), and it expresses a complete thought.

To double-check your answer, you can examine if the text has a clear subject and predicate and if it can stand alone as a complete idea. In this case, the text meets those criteria and is, therefore, a sentence.

Yes, you're correct! "That she was the only one who came made a huge difference in our plans" is a complete sentence. It has a subject ("that she was the only one who came") and a predicate ("made a huge difference in our plans"), which makes it a sentence.

To check if a group of words is a sentence or a clause fragment, you can apply a simple test. Try replacing the subject or the verb with a pronoun or a form of "be" (such as "is," "are," "was," or "were"). If the modified sentence still makes sense, then the original group of words is a sentence. In this case, you can replace "that she was the only one who came" with "it" to form the sentence "It made a huge difference in our plans." This confirms that the original group of words is indeed a sentence.
