what is the answer

The answer is that the sentence is grammatically correct and does not contain a double negative.

The given statement contains a double negative. In standard English grammar, double negatives cancel each other out and create a positive meaning. So, the sentence could be rephrased as: "We didn't tell anybody about the broken window."

It seems that you have provided a sentence and are asking about its grammatical elements. Let's break it down and identify the different components.

The sentence "We didn't tell anybody about the broken window" consists of a subject ("we") followed by a verb phrase ("didn't tell") and an object ("anybody") that is complemented by a prepositional phrase ("about the broken window").

Now let's address the elements you mentioned:

1. Double Negative: The sentence contains the negative adverb "didn't" followed by the negative pronoun "anybody." This creates a double negative construction. In standard English grammar, double negatives cancel each other out and result in a positive meaning. Therefore, the sentence can be understood as meaning that "we told somebody about the broken window."

2. Incorrect Intensive Pronoun: It seems that you mentioned an intensive pronoun. However, there are no intensive pronouns in the given sentence. Intensive pronouns like "myself," "yourself," or "herself" are used to emphasize a noun or pronoun and are not present in this sentence.

3. Slang: The sentence appears to be written in standard English and does not contain any slang terms.

To summarize, the given sentence has a double negative construction, does not include any intensive pronouns, and does not contain any slang terms.
