Expert writing Tips

Best practice

Always use "have" after modal verbs like "should", "could", "would", and "must" to form the perfect infinitive. For example, use "she should have known" instead of the incorrect "she should has known".

Common error

Avoid using "has" after modal verbs such as "should", "could", or "would". "Has" is typically used with third-person singular subjects (he, she, it) in the present perfect tense, whereas "have" is used with modal verbs to form perfect infinitives, regardless of the subject. Therefore, the construction should always be "should have", not "should has".
