Common word you will never hear the Royal Family use for unusual reason

Being part of the Royal Family comes with many rules and traditions that must be followed.

Some are there to make things a bit more easier - like how the royal children are addressed when at school.

Another rule they have, and perhaps one that's more specific, is around travel and making sure those in succession to the throne don't travel together.

For Prince George, who turns 12 next year and is second in line to the throne, this will mean he no longer travels alongside his father Prince William and his siblings, but will need to travel separately.

However, there are also rules that extend towards certain words that the Royal Family have to avoid.

For bathrooms, you'll never catch a royal using the words 'the toilet' but instead they'll opt for 'lavatory' or 'loo', which is thought to be due to the words 'toilet' previously having French links, and in the past, the British and French royal families weren't always friendly, according to The Mirror.

You'll also never find a royal referring to a room as 'the lounge' but instead they'll always refer to it as a 'sitting room' or a 'drawing room', especially as royal residences like Buckingham Palace have so many.

Another word the royals don't use is 'tea', but instead refer to their evening meal as 'supper' or 'dinner'.

For female members of the Royal Family, they also don't wear 'perfume' but instead wear 'scent'.

Whilst many of us will naturally call our parents 'Mum and Dad', the royals again have a different way of doing things.

Instead they have different names, as Prince George, Princess Charlotte and Prince Louis are known to call Prince William 'Papa' and to call Kate 'mummy'.

King Charles II has also refered to his mother, Queen Elizabeth II, as 'mummy' or 'mama'.

It's not just language, but there are even rules about how royals can greet people.

A handshake or a wave hello is not enough, as royal guidelines mean that they will always maintain eye contact throughout and will keep a handshake to two shakes minimum.

I suppose with meeting so many people at events and appearances, shaking hands will need to be kept brief so they can make sure they get to everyone they need.

Yet it's also reportedly to stop a royal from giving 'preferential treatment' to one person in particular, according to Harper's Baazer.

All in all, there's a lot to remember.
