Even in advanced upper-level academics, it is common for a student writing assignment to contain errors in subject/verb agreement. What exactly does it mean to have subjects and verbs agree? Basically, it means that a singular subject needs a verb in the singular form, and a plural subject needs a verb in the plural form. Here are some basic examples of subject/verb agreement:
- Singular subject and Singular verb
