forbid or prohibit?

Anyone in charge can forbid something. Prohibit is the official word for rules and laws.

Both words mean saying no to something, so children often think they are just a short and a long way of saying the same thing. The difference is who is saying no.

Forbid is the everyday word. A parent can forbid screens at the dinner table; a teacher can forbid talking during a test. Rules can forbid things too, but forbid works perfectly well for one person giving an order.

Prohibit is official. It is the word on signs and in rules: 'Ball games prohibited', 'Parking is prohibited outside the school gates'. It would sound very odd for Mum to say she prohibits you from eating biscuits before tea. If you can imagine the words printed on a notice, prohibit fits.

Why it costs marks

Verbal reasoning questions often pair a word with its most formal or most everyday match. Knowing that prohibit belongs with laws and notices helps a child choose between close options, and use the right tone in their own writing.
