QUESTION What is the correct question tag for the sentence: “She ought to apologise, …”? Technically, for modal verbs such as “ought to”, “have to” and “used to”, the tag uses the modal verb without “to”. The “to” is actually part of the main verb. So, the correct form would be: She ought to apologise, oughtn’t she? This follows the same pattern as: She has to apologise, hasn’t she? With “used to”, the techncally correct form is: She used to apologise, usedn’t she? However, most native English speakers today would not use this form. We would say: She used to apologise, didn’t she? #Mike_Mendis ⭕️Unknown English
