Определение и Значение "do-support"

What is "do-support"?

Do-support is a grammatical phenomenon in English where the auxiliary verb "do" is used to form questions, negatives, or emphatic statements when there is no other auxiliary verb present. For example, in the sentence "He likes ice cream," the question form would be "Does he like ice cream?" Here, "does" serves as the auxiliary verb that helps form the question. Similarly, in the negative sentence "He does not like ice cream," "does" is used to express negation. Understanding do-support is important for grasping how English structures questions and negative sentences, making it easier to communicate effectively.
