Transcript Double Negatives

"Today looks beautiful! There isn’t going to be no rain! So get out there and enjoy!" Uh-oh! Pip appears to be sending mixed messages about the weather! If he wants to make sure he's communicating properly, Pip needs to learn about double negatives. Double negatives are sentences that contain two negative words in one thought. Negative nouns are words such as no one, nobody, nothing and nowhere. Negative verbs include does not, was not, can’t, isn’t, and shouldn’t. Negative adverbs include words like no, not, never, and rarely. When two negative words are combined in a sentence, they cancel each other out and lead to a weakened positive statement. As a result, the sentence is grammatically incorrect and difficult to understand. Double negatives make your meaning unclear because they send the opposite message than you intended. For example, "I don't want nothing." actually means you want something. Look at the statement made by Pip. He said, "There isn’t going to be no rain," while trying to convey that the weather will be sunny. The words "isn't" and "no" contradict each other therefore forming a positive statement. If there isn't going to be no rain happening, we're actually saying that it is going to rain. There are a couple of ways to correct double negatives. First, we could change the second negative word to a positive word. Positive words include: any, anything, always, some, something, and ever. There isn't going to be no rain would become "there isn't going to be any rain". Or, we can remove a negative word, like 'no' and the sentence will say, 'there isn't going to be rain.' Let's practise with some examples. Which sentences are written correctly? The correct sentences are "I have no homework to do," and "I don't have any homework to do." These statements only have one negative, so they communicate that there isn't homework. In the sentence, "I don't have no homework to do," there is a "don't" and a "no". This communicates that you actually have homework to do. Which of these sentences are written correctly? The correct sentences are "We saw nobody at the movies," and "We didn't see anybody at the movies." Sometimes, we have to change the tense of a word when correcting double negatives in sentences, like see to saw. While Pip finishes up the weather report, let's review. Remember, when two negative words are combined in a sentence, they cancel each other out and lead to a weakened positive statement. As a result, the sentence is grammatically incorrect and difficult to understand. We should avoid using double negatives in our sentences in order to communicate clearly with others. "I thought you said it wasn’t going to rain today."

  • Are these words positive or negative words?

    Hints

    Negative words negate something. They help show that the opposite of something is true.

    In the sentence, "He does not like his new t-shirt." the word not is negative.

    With the word not in the sentence, the sentence means he dislikes his new t-shirt.

    Positive words help show something is true.

    For example, in the sentence, "She has some apples." the word some is a positive word.

    It shows she has more than one apple.

    This problem has 4 negative words and 4 positive words.

    In the sentence, "I can't see any clouds in the sky." can't is a negative word and any is a positive word.

    Solution

    Always, any, ever and something are positive words They help show something is true.

    Nobody, rarely, never and can't are negative words. They help show the opposite of something is true.
