Respuesta :

In writing S/V, the teacher is telling the student to revise the sentence's subject/verb agreement.

If the student wrote a sentence in which the subject and verb did not agree with one another (for example, writing: "He were not at home"), then the teacher would indicate an error in subject/verb agreement.

Answer:

The teacher is trying to say that there is a subject-verb error

Explanation:

When checking the writing in a piece of work, there are specific symbols to put little notes where the errors happen, the abbreviation S/V is used when there is a subject-verb agreement mistake, this is when it is used the incorrect verb form with any of the persons in the speech, for example, "The day is beautiful" instead of the correct form "The day is beautiful"
