Frequently Asked Questions

Use the subjunctive or 'should' in formal British English: 'It is necessary that he be informed' (subjunctive) / '...that he should be informed'. In American English, the subjunctive is common. In informal contexts, the indicative is often used: 'It is necessary that he is informed'.
Yes, but it's less common as necessity is often seen as binary. 'More necessary' is used in comparative contexts, e.g., 'Food is more necessary than luxury items.' 'More essential' or 'more critical' are often preferred.
Rarely in modern English. The noun form 'necessaries' exists but is archaic/formal for 'essential items' (e.g., 'the necessaries of life'). The usual noun is 'necessity'.
