What is a double negative?

Learn why two negatives don't always make a positive in the world of grammar.

I n the real world, purging negativity is an important skill for a happy life. In the grammar world, purging double negativity is crucial for clear and concise writing. Double negatives are redundant thoughts made of multiple negative words; these result in complicated and confusing sentences. However, they aren't not useful. Every once in a while, an appropriately used double negative can improve your writing, but those occasions are rare.

A double negative is any statement with two negative words. A person might say, for example, "I didn't see nobody." The two negatives are "did not" and "nobody." The problem is that double negatives muddle the intentions, resulting in the opposite meaning. "I didn't see anybody" would be clearer. Think back to math class — multiplying two negative numbers together cancels out the negative and turns it into a positive. It's the same with words. Two negatives cancel each other out and turn the statement into a positive. Combining "didn't" and "nobody" flips the meaning to imply the speaker did see somebody, which wasn't the goal of the statement.
