Can someone explain how to make questions with be, have, and modal verbs?

Asked byAmelia EditorPosted Apr 1, 2026 5:02 AM3 answers27 upvotesCanonical URL

I'm having trouble forming questions in English, especially when it comes to using ‘be’, ‘have’, and modal verbs like ‘can’ or ‘should’. For example, I get confused if I should say, "Is he your brother?" or "He is your brother?" The same thing happens with sentences like, "Have you finished your homework?" versus "You have finished your homework?" Also, when I use modal verbs, I'm not sure if the order changes even more. Should it be "Can you help me?" or "You can help me?"

I'm not sure about the correct word order in these cases. Could someone please explain how to form these types of questions, and maybe point out what I’m doing wrong in my examples?

Learning for everyday conversation. British English preferred but American rules also helpful.

To form questions with 'be', 'have', and modal verbs, you usually use inversion: the auxiliary or modal verb comes before the subject. Here are the main patterns:

1. 'Be' verb pattern:

  • Question: [Be] + [Subject] + [Rest of sentence]?
  • Example: "Are you ready?" (Correct) vs. "You are ready?" (Less formal; only used in surprise or echo situations.)

2. 'Have' as an auxiliary (for perfect tense):

  • Question: [Have/Has] + [Subject] + [Past participle]?
  • Example: "Have they eaten?" (Correct) vs. "They have eaten?"

3. Modal verbs (can, should, must, etc.):

  • Question: [Modal] + [Subject] + [Verb]?
  • Example: "Should we leave now?" (Correct) vs. "We should leave now?"

Practice: Pick three sentences you say every day. Write them as statements, then invert according to the pattern to make questions, e.g., "He is at home." → "Is he at home?"

Tip: When unsure, put the auxiliary or modal first. In spoken English, statements with upward intonation sometimes act as questions, but using inversion is much clearer and more correct.

Let's compare statement and question forms to understand how to form questions with 'be', 'have', and modal verbs:

1. Using 'be':

  • Statement: "She is coming tonight."
  • Question: "Is she coming tonight?"
    Explanation: For questions, switch the position of 'be' and the subject.

2. Using 'have' (for possession in British English):

  • Statement: "They have a car."
  • Question: "Have they a car?" (formal/British) or "Do they have a car?" (common in both British and American English)

3. Using modal verbs:

  • Statement: "You could join us."
  • Question: "Could you join us?"

Practice Step: Pick a statement using 'be', 'have', or a modal verb. Try making the question by moving the verb before the subject. Double-check: If it sounds like a statement, see if you need to invert.

Corrective feedback: If you write "You are hungry?", ask yourself: "Did I place 'are' before the subject?" If not, revise to "Are you hungry?".

A practical way to master question word order with 'be', 'have', and modal verbs is to drill by contrasting correct and incorrect forms:

Be-verbs:

  • Correct: "Were they here?"
  • Incorrect: "They were here?" (this is a statement or used for surprise, not a standard question)

Have as auxiliary (present perfect):

  • Correct: "Has she finished her assignment?"
  • Incorrect: "She has finished her assignment?"

Modal verbs:

  • Correct: "Will you join us?"
  • Incorrect: "You will join us?"

Self-check: For a question, is the first word a verb (be, have, or modal) followed by the subject? Try reading aloud both options to hear which version matches common conversation.

Practice tip: Write five statements, then change them into questions by moving the verb before the subject. Example: "We should start now." → "Should we start now?"
