Question

Fill in the blank in the following sentence with the correct alternative: 
I did not inform ____ at all.

Accepted Answer

Here's a detailed explanation for why "Anybody" is the correct option and why the others are incorrect:

**Explanation for Option 1 (Anybody) being correct:**

1.  **Usage in Negative Sentences:** In English, indefinite pronouns like "anybody" (or "anyone") are typically used in negative sentences, questions, and conditional clauses. The sentence "I did not inform..." is a negative sentence because of "did not."
2.  **Meaning:** "Anybody" in a negative context means "no person" or "not a single person." So, "I did not inform anybody" means "I informed no person."
3.  **Reinforcement with "at all":** The phrase "at all" is used to emphasize a negative statement. It perfectly complements "anybody" in this context, reinforcing the idea that absolutely no one was informed.
    *   Example: "I did not inform anybody at all." This is a grammatically correct and natural-sounding sentence.

**Explanation for why other options are incorrect:**

*   **Option 2 (Any):**
    *   "Any" is primarily used as a determiner (e.g., "any person," "any money") or as a pronoun referring to things or an unspecified quantity (e.g., "Do you have any?").
    *   When referring to people in a negative sentence, "any" usually needs to be followed by a noun (e.g., "I did not inform any *person*").
    *   Using "I did not inform any" by itself to refer to people is grammatically incomplete and awkward.

*   **Option 3 (None):**
    *   "None" is an indefinite pronoun meaning "not one" or "not any." It is inherently a negative word.
    *   Using "none" with "did not" would create a double negative ("I did not inform none"). In standard English, double negatives are generally considered grammatically incorrect because they cancel each other out, implying the opposite meaning (e.g., "I did not inform none" would technically mean "I did inform some").

*   **Option 4 (Nobody):**
    *   "Nobody" is an indefinite pronoun meaning "no person." It is also inherently a negative word.
    *   Similar to "none," using "nobody" with "did not" would create a double negative ("I did not inform nobody"). This is grammatically incorrect in standard English and would imply "I did inform somebody."

Therefore, "Anybody" is the only option that correctly completes the negative sentence without creating a double negative or being grammatically incomplete.
