Negative questions are questions that contain 'not' in the question form: 'Don't you know?', 'Isn't she coming?', 'Didn't they finish?'. They are common in everyday speech and carry a particular meaning — the speaker expects the answer to be 'yes', or is expressing surprise. However, they create a serious and persistent problem for learners: how to answer them. In many languages, the answer 'yes' or 'no' refers to whether the statement in the question is true. In English, the answer refers to the situation — 'yes' means 'the situation is positive' and 'no' means 'the situation is negative', regardless of how the question was phrased. This single principle resolves most of the confusion students experience.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
What is the speaker's expectation in each question? If both questions are answered truthfully with 'Yes, I know the answer', does the answer change? What about if both are answered with 'No, I don't know'?
The positive question is neutral — the speaker has no expectation. The negative question carries an expectation: the speaker thinks you probably know. But the answer does not change based on how the question was asked. If you know the answer, you say 'Yes, I do' to both questions. If you don't know, you say 'No, I don't' to both. The question form affects meaning and tone, not the answering rule. Students who say 'Yes, I don't' are answering the word 'don't' rather than the situation — the key teaching insight.
Didn't they finish the exam?
Yes, they did. (they DID finish)
No, they didn't. (they did NOT finish)
Look at the answers. What does 'yes' refer to in each case? What does 'no' refer to? Does the 'not' in the question affect the answer?
'Yes' always means the situation is positive — the thing happened, the quality exists. 'No' always means the situation is negative — the thing did not happen, the quality does not exist. The 'not' in the question does not flip the answer. 'Yes, she is' = she IS a good teacher (agreeing with the positive idea). 'No, she isn't' = she is NOT a good teacher (confirming the negative). The answering rule is entirely about the real-world situation, not about the form of the question.
Can't they stay? (contraction first)
Can they not stay? (full form, more emphatic)
Look at the two forms of each negative question. What is different about the word order? When might a speaker use the full form instead of the contraction?
In the contracted form ('Isn't she coming?'), the contracted auxiliary + not moves to the front as a single unit. In the full form ('Is she not coming?'), the auxiliary moves to the front and 'not' stays close to the subject. The full form sounds more formal or emphatic — it is used in careful speech or writing, or when the speaker wants to stress the negative element. In everyday speech, the contracted form is far more common. Both forms are grammatically correct; students should know both exist but need only produce the contracted form at B1 level.
| Tense / Form | Use / Meaning | Example | Key time words |
|---|---|---|---|
| Positive question | Negative question | Yes answer | No answer |
| Do you know? | Don't you know? | Yes, I do. (I know) | No, I don't. (I don't know) |
| Is she coming? | Isn't she coming? | Yes, she is. (she is coming) | No, she isn't. (she isn't coming) |
| Did they finish? | Didn't they finish? | Yes, they did. (they finished) | No, they didn't. (they didn't finish) |
| Can he teach it? | Can't he teach it? | Yes, he can. (he can) | No, he can't. (he can't) |
| Will it rain? | Won't it rain? | Yes, it will. (it will rain) | No, it won't. (it won't rain) |
The answering rule for negative questions is one of the most cross-linguistically difficult features of English, because many languages answer based on the form of the question rather than the situation. In French, 'si' is used to disagree with a negative question; in Swahili and many other languages, 'yes' can mean 'yes, you are right that I don't'. In English, the rule is purely situational: think about what is true, then answer with 'yes' if it is positive and 'no' if it is negative. A classroom strategy that helps: teach students to answer negative questions by first ignoring the 'not' and asking themselves 'what is the real situation?'. If the situation is positive, say 'yes' + the positive auxiliary. If the situation is negative, say 'no' + the negative auxiliary. The question's form is irrelevant to this decision.
When answering a negative question: 1. Ignore the 'not' in the question 2. Ask yourself: what is the real situation? 3. Is the situation positive? → Answer 'Yes' + positive auxiliary (Yes, I do / Yes, she is) 4. Is the situation negative? → Answer 'No' + negative auxiliary (No, I don't / No, she isn't) Never say 'Yes, I don't' or 'No, she is' — these mix positive and negative incorrectly.
Write the correct answer to each negative question. The situation is given in brackets.
Each sentence or exchange contains one error. Find and correct it.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — Positive to negative question (5 min): Write three positive questions on the board. Ask students to convert each to a negative question. Establish the rule: the contracted negative auxiliary moves to the front as a unit. Check: does the main verb stay in base form?
STEP 2 — What does the speaker expect? (4 min): Give three negative questions and ask students: what does the speaker think is true? What are they surprised about? This builds the meaning — negative questions are not neutral; they carry an expectation. Use situations from school life to make it concrete.
STEP 3 — The answering rule — ignore the 'not' (6 min): This is the main teaching step. Write a negative question on the board, then draw two columns: POSITIVE SITUATION and NEGATIVE SITUATION. Show the correct answer for each column. Emphasise: look at the situation, not the question form. Never say 'Yes, I don't.'
STEP 4 — Answer drill (5 min): Call out a negative question and describe the situation. Students must give the correct short answer. Go round the class quickly, varying the situations. Correct immediately when a student mixes positive and negative in their answer.
STEP 5 — Consolidate (5 min): Ask students to write two negative questions about school life and the correct answers for both the positive and negative situation. Students share with a partner who checks the formation and the answering rule.
