Expert writing Tips

Best practice

Always use the base form of a verb after modal verbs such as "could", "should", and "might". The correct form is "could vary", not "could be vary".

Common error

Avoid using "be" before the base form of the verb after modal verbs like "could". The structure "could be vary" is grammatically incorrect. Use "could vary" instead.
