Expert writing Tips
Best practice
When using "it is necessary that", ensure the clause following 'that' uses the subjunctive mood, especially in formal writing. For example, 'It is necessary that he be present' rather than 'It is necessary that he is present'.
Common error
A common error is to use the indicative mood instead of the subjunctive after "it is necessary that". Avoid saying 'It is necessary that he is there'; instead, use the subjunctive: 'It is necessary that he be there'.
