Expert writing Tips

Best practice

Always use the correct subject-verb agreement. "I" is a first-person singular pronoun and requires the base form of the verb, which is "know". Therefore, use "I know that".

Common error

Avoid using "I knows that". The correct form is "I know that". Using "knows" with "I" is a common error among non-native English speakers. Double-check your subject-verb agreement when writing.
