A. Double Negative

A.

Double Negative

In order to determine whether each sentence has a double negative, an incorrectly formed intensive pronoun, or slang, we need to analyze the given sentence.

The sentence in question is: "She couldn't hardly fit the book in her purse."

To identify if it contains a double negative, we look for the presence of both "not" and "hardly" or any other negative words. In this case, we have "couldn't" (which is a contraction of "could not") and "hardly." These two negatives combined ("could not" and "hardly") create a double negative.

So the correct answer is:
A. Double Negative

Explanation on how to determine a double negative:
To determine if a sentence contains a double negative, look for the use of negative words such as "not," "no," or any word with a negative prefix (e.g. "un-", "dis-", etc.). If two negatives are used in a sentence without a proper reason, it forms a double negative.

Remember that in standard English, double negatives are typically considered grammatically incorrect and can create confusion or change the meaning of a sentence.
