What is do-support in English, and when does it typically appear in a child’s speech?

• A. The use of 'do' as a main verb.
• B. The omission of the auxiliary 'do' in questions.
• C. The use of 'do' to form statements.
• D. The auxiliary 'do' used to form questions/negatives; emerges as children acquire auxiliary systems.

Answer: (D)

Do-support is the use of the auxiliary do (do/does/did) to form questions and negatives when there isn’t another auxiliary already in the verb phrase. It acts as a helper that lets you invert the subject for questions and attach not for negatives, as in “Do you want some?” or “I do not want it.” In child speech, you see this emerge as kids learn how to use auxiliary verbs. They often start with simple statements or non-inverted questions and negatives, then gradually begin inserting do to form proper questions and negatives. This development typically appears in the preschool years, around age three, as the child’s grasp of English auxiliary systems grows.
