Negative Sentences: Definition, Structure & Examples

What Are Negative Sentences?

At their core, negative sentences are statements that express the opposite of an affirmative (positive) sentence. They convey a sense of not, no, never, none, or absence.

In every language, the ability to say “no” or to express a denial is just as crucial as saying “yes.” Negative sentences are fundamental to communication, allowing us to deny facts, refuse requests, express absence, or simply state what isn’t true. They are essential for:

• Denying actions or facts: “I did not go to the store.”
• Expressing absence or lack: “There isn’t any milk left.”
• Stating prohibitions or rules: “You must not touch that.”
• Contradicting a previous statement: “No, that is not what I said.”
• Expressing disagreement: “I don’t agree with that.”

How Negative Sentences Are Formed in English

English primarily uses the word not to form negative sentences, often in conjunction with auxiliary verbs (also known as helping verbs).

1. Using not with Auxiliary Verbs

This is the most common way to negate a verb in English.

• With do, does, did (for Simple Present and Simple Past Tenses): When the main verb is not a form of “to be” or a modal verb, we use do, does, or did as an auxiliary verb, followed by not, and then the base form of the main verb.

  • Affirmative: “I like coffee.”
  • Negative: “I do not like coffee.” (or I don’t like coffee.)
  • Affirmative: “She lives here.”
  • Negative: “She does not live here.” (or She doesn’t live here.)
  • Affirmative: “They went home.”
  • Negative: “They did not go home.” (or They didn’t go home.)

• With Modal Verbs (can, will, should, must, might, could, would, shall): Simply place not directly after the modal verb.

  • Affirmative: “You can do it.”
  • Negative: “You cannot do it.” (or You can’t do it.)
  • Affirmative: “I will call you.”
  • Negative: “I will not call you.” (or I won’t call you.)
  • Affirmative: “We should leave.”
  • Negative: “We should not leave.” (or We shouldn’t leave.)

• With Forms of to be (am, is, are, was, were): Place not directly after the “to be” verb.

  • Affirmative: “He is happy.”
  • Negative: “He is not happy.” (or He isn’t happy.)
  • Affirmative: “They were here.”
  • Negative: “They were not here.” (or They weren’t here.)

• With have as an auxiliary verb (for Perfect Tenses): Place not directly after the have auxiliary.

  • Affirmative: “I have seen that movie.”
  • Negative: “I have not seen that movie.” (or I haven’t seen that movie.)
  • Affirmative: “She had finished the work.”
  • Negative: “She had not finished the work.” (or She hadn’t finished the work.)

2. Using Negative Words

English also uses specific words that inherently carry a negative meaning, often without needing not. When these words are used, the sentence is already negative, and adding not would typically create a double negative, which is generally considered ungrammatical in standard English.

Common negative words include:

• never (at no time): “I never eat meat.”
• no one / nobody (no person): “No one came to the party.” / “Nobody knows the answer.”
• nothing (no thing): “He said nothing.”
• nowhere (no place): “They found the keys nowhere.”
• none (not any): “I have none left.”
• hardly, scarcely, barely (almost not): “I hardly know him.” (meaning I almost don’t know him.)

Important Note on Double Negatives: In standard English, avoid using two negative words in the same clause if you intend a single negation. For example, instead of “I don’t know nothing” (which means I know something), say “I don’t know anything” or “I know nothing.”

Conclusion

Negative sentences are a cornerstone of effective communication, enabling us to express limitations, denials, and contradictions. While the basic formation with not and auxiliary verbs is straightforward in English, understanding the role of other negative words is crucial for clear and grammatically correct expression.
