Expert writing Tips

Best practice

Always use the correct form of the verb after "must". "Must" is a modal verb and should be followed by the base form of the verb (e.g. "must leave"), not the past participle (e.g. "left").

Common error

Avoid using past participle forms after "must". Remember that "must" requires the base form of the verb. For example, it's "must go", not "must went", and "must leave", not "must left".
