Expert writing Tips

Best practice

When writing, ensure "must" is followed by the base form of the verb (e.g., "You must attend", not "You must to attend").

Common error

Avoid using "must" with other modal verbs (e.g., "must should"). "Must" already expresses necessity, so adding another modal can create redundancy or grammatical errors. For instance, it is more correct to say "You should attend" or "You must attend" rather than "You must should attend".

Linguistic Context

The modal verb "must" primarily functions to express obligation, necessity, or logical deduction. Ludwig AI identifies its use in contexts ranging from stating requirements to drawing conclusions based on evidence. For example, "You must submit your entry" shows obligation, while "That must have hurt" indicates deduction.
