Expert writing Tips

Best practice

Use "must not go" to convey a strong sense of prohibition or inadvisability. It's more forceful than "should not go" and implies serious consequences if ignored.

Common error

Avoid using "must not go" in everyday, informal situations where a softer recommendation is more appropriate. Opt for "should not go" or "can't go" to maintain a natural tone.
