Expert writing Tips
Best practice
Ensure subject-verb agreement. When referring to a single study, use the verb form that agrees with a singular subject, such as "demonstrates" instead of "demonstrate".
Common error
Avoid using the base form of the verb (e.g., "demonstrate") when the subject is singular (e.g., "a study"). Always use the correct conjugation (e.g., "demonstrates").
