Meghan Markle may be engaged to Prince Harry, and moving into Kensington Palace, but that doesn’t mean she’ll ever be a princess.

As Vogue reported, Markle can never be named a princess as it goes against British monarchy protocol. In fact, the only people who can hold the title of “prince” or “princess” are those born into it — like Prince Harry, William, and William’s children, Princess Charlotte and Prince George (and baby number three on the way).

Meghan isn’t the only one being left out in the cold when it comes to titles. Her future sister-in-law Kate Middleton isn’t a princess either — her title is actually Her Royal Highness, Catherine Duchess of Cambridge. To keep things smooth, Prince William even added Duke of Cambridge to his own title after Queen Elizabeth bestowed upon them the dukedom title as a wedding gift.

And like with William and Kate, the Queen is expected to anoint Harry and Meghan with the title of Duke and Duchess on their wedding day. According to Royal Central, the pair may become the Duke and Duchess of Sussex, a title that hasn’t been filled since 1843.

“Most likely, he will be created a Duke. Sussex is available so [Meghan Markle] would be HRH the Duchess of Sussex,” Royal Historian Marlene Koenig wrote on Royal Musings. “Her rank would be a princess by marriage of the United Kingdom, Great Britain and Northern Ireland.”

Of course this title confusion is nothing when compared to Prince Philip's massively long moniker. While commonly known simply as Prince Philip or the Duke of Edinburgh, Philip’s title is actually more than 100 words long. It reads:

His Royal Highness The Prince Philip, Duke of Edinburgh, Earl of Merioneth, Baron Greenwich, Royal Knight of the Most Noble Order of the Garter, Extra Knight of the Most Ancient and Most Noble Order of the Thistle, Member of the Order of Merit, Grand Master and First and Principal Knight Grand Cross of the Most Excellent Order of the British Empire, Knight of the Order of Australia, Additional Member of the Order of New Zealand, Extra Companion of the Queen’s Service Order, Royal Chief of the Order of Logohu, Extraordinary Companion of the Order of Canada, Extraordinary Commander of the Order of Military Merit, Lord of Her Majesty’s Most Honourable Privy Council, Privy Councillor of the Queen’s Privy Council for Canada, Personal Aide-de-Camp to Her Majesty, Lord High Admiral of the United Kingdom.
